Measurement of the rmsvalue of phase 1 current, which integratesthe influence of harmonics up to number 21,takes into account the wave form to calculate heatrise in balanced three-phase loads.Taking into account of negative sequence currentNegative sequence current is a significant factorin calculating heat rise in rotating machines.The rotating field that corresponds to the negativesequence current creates a double frequency rotatingcurrent that causes major losses.This is why the thermal overload function takesinto account the following equivalent current:Ieq 2 = I 2 + K.Ii 2I is the greatest of the following values:I1, I2, I3 et I1rmsIi is the current negative sequence.Adjust is the negative sequence factor(weighting coefficient).Operation curveThe protection gives a tripping order when the heat rise heating calculatedaccording to the measurement of an equivalent current Ieq is greater thanthe OL set point.The highest permissible continuous current is I = Ib e.The protection tripping time is set for the time constant T.The heat rise calculated depends on the current absorbed <strong>and</strong> the previous heatrise status.c The cold curve defines the protection tripping time according to a heat riseof 100%.10 1 cold curve1010 -110 -210 -3 0 510Influence of the time constantThe time constant depends on the equipment's thermal characteristics.It takes heat release <strong>and</strong> cooling into account.For a non-ventilated rotating machine, cooling is more effective when the machineis running than when it is stopped due to the ventilation caused by rotation.c Equipment running <strong>and</strong> stopping are calculated according to the current value:v running if I > 0.015Ib,v stopped if I < 0.015Ib.Two time constants can be set:c T1: heat rise time constant: concerns equipment that is running.The T1 thermal time constant is the time needed for the equipment under ratedload to reach 0.63 times the rated heat rise (obtained after an infinite time).c T2: cooling time constant: concerns equipment that is stopped.The T2 time constant is the time needed after stopping for the initial heat risein the protected equipment to drop to 0.36 times the rated heat rise.heating10.630T1Heat rise time constant.ttT = Loghot curvetT = LogleqIbleqIbleqIbleqIb22- OL2- 12- OLheating10.360T2Cooling time constant.t<strong>Protection</strong> functions2/21

If that is the case, theprotection is disabled: all the outputs are set to zero.Application, settingThe rate of change of frequency protectionis a complement to the underfrequency <strong>and</strong>overfrequency protections used to detect lossof mains protection or load shedding.The protection settings must be consistent with theother frequency protections.Loss of mains applicationThis function is used on the incomer of an installationwhich includes a generator that can be run in parallelwith the mains.Its role is to detect the loss of the mains, resulting inisolated operation of the generator. If the powerthrough the mains prior to isolated generatoroperation is not zero, the generator frequency varies.The rate of change of frequency protection detectsthis conditions more rapidly than a conventionalfrequency protection would.Other disturbances such as short-circuits, loadchanges <strong>and</strong> switching can cause frequency changes.The low set point may be temporarily reached duringsuch conditions so a time delay is necessary.In order to maintain the frequency derivativeprotection’s advantage of speed compared toconventional frequency protections, a second, higherset point with a short time delay may be added.Overfrequency <strong>and</strong> underfrequency protections in loss of mains applications areconventionally set to the fundamental frequency + 0.5 Hz or – 0.5 Hz. Based onthe assumption of a constant rate of change of frequency, the tripping times of therate of change of frequency protection <strong>and</strong> the underfrequency <strong>and</strong> overfrequencyprotections may be shown on the same graph:tripping time (s)21,81,61,41,210,80,60,40,200overfrequency protection: Fs = 50.5 Hz T = 0.1srate of change of frequency protection:dFs/dt = 0.15 Hz/s T = 0.5 srate of change of frequency protection:dFs/dt = 0.15 Hz/s T = 0.5 s0,5 1 1,5 2 2,5 3 3,5 4 4,5 5dF/dt (Hz/s)Comparison of an overfrequency protection <strong>and</strong> two rate of change of frequency protectionsset points. The rate of change of frequency protection detects isolated generator operationfaster than a frequency protection does.In fact, the rate of change of frequency is not constant. Often the rate of changeof frequency is the highest at the beginning of the disturbance <strong>and</strong> then decreases,which extends the frequency protection tripping time but does not affect thetripping time of the rate of change of frequency protection.c Low set pointv If rules have been established by the utility, they should be followed.v If no rules are given by the utility:- If the maximum rate of change of frequency on the mains in normal conditions isknown, dFs/dt should be set above it.- If no information on the mains is available, the low set point may be establishedbased on generator data. A good approximation of the rate of change of frequencyfollowing a loss of mains accompanied by a load change ∆P is:df ∆ P * Fn= -dt 2 * Sn * HwithSn: Rated loadFn: Rated frequencyH: inertia constant MW*s/<strong>MV</strong>ATypical inertia constant value:0.5 i H i 1.5 for diesel <strong>and</strong> low rated generators (i 2 <strong>MV</strong>A)2 i H i 5 for gas turbine <strong>and</strong> medium rated generators (i 40 <strong>MV</strong>A)H = 1 2J x Ω 2SnExampleswithJ = inertia momentΩ = machine speedrated load 2 <strong>MV</strong>A 20 <strong>MV</strong>Ainertia constant 0.5 s 2 sload variation 0.1 <strong>MV</strong>A 1 <strong>MV</strong>Adf/dt - 2.5 Hz/s - 0.6 Hz/s2/48 <strong>Protection</strong> functions


c Low set point time delayFor good protection stability in the event of short-circuits or transient disturbances,the recommended time delay is 300 ms or more.v If an automatic recloser is in service upstream from the installation, detection ofisolated generator operation <strong>and</strong> coupling circuit breaker opening should takeplace during the recloser isolation time.c High set pointThe second set point may be chosen so that the rate of change of frequencytripping curve remains below the underfrequency <strong>and</strong> overfrequency protectioncurves.If the frequency protections are set to Fn+/-0.5 Hz <strong>and</strong> if the low set point timedelay of the rate of change of frequency protection is T, the high set point could beset to 0.5/T.c High set point time delayNo particular recommendations.c Recommendations on setting when no information is availablesettings rated generator rated generator2 - 10 <strong>MV</strong>A > 10 <strong>MV</strong>AF581 dFs 0.5 Hz/s 0.2 Hz/sT 500 ms 500 msF582 dFs 2.5 Hz/s 1 Hz/sT 150 ms 150 msc Precautions for use:At the time the generator is being coupled to the mains, power oscillations mayappear until the generator becomes fully synchronized.The rate of change of frequency protection is sensitive to this phenomenon.It is advisable to inhibit the protection for a few seconds after the closingof the circuit breaker.Load shedding applicationThe rate of change of frequency protection may also be used for load sheddingcombined with underfrequency protections.In such cases, it equips the installation’s busbar protection.Two methods are available:c acceleration of load shedding:The rate of change of frequency protection comm<strong>and</strong>s load shedding. It acts fasterthan an underfrequency protection does <strong>and</strong> the value measured (df/dt) is directlyproportional to the load to be shed.c inhibition of load shedding:The rate of change of frequency protection inhibits load shedding in the case of afast change in frequency. This method is used when it is considered that a strongchange in frequency is not due to an overload but to a production facilityinsufficiency. Load shedding in those conditions is unnecessary.When that is the case, the underfrequency protections must be time-delayedin order to be sure that the rate of change of frequency protection inhibition orderwill be conveyed before the tripping of the underfrequency protection(underfrequency protection tripping time setting T = 0.2 s).In both of these applications, only negative rates of change of frequency protectionare used.<strong>Protection</strong> functions2/49

Moto-generator differentialANSI codefunction n°Operation87G - 87MF621Motor-generator differential protection is 3-phase.It is based on phase by phase comparison of thecurrents on either side of the windings of a generatoror motor.IPercentage-based differentialThe protection picks up when the difference between–> –>currents I - I’ for at least one phase is above theoperation set point.The set point is defined by the curve opposite(based characteristic curve). It has an adjustableminimum value <strong>and</strong> depends on the through current.It = I + I’2The based characteristic curve comprises twohalf-curves defined by the following inequations:half-curve 1:Id x 2 – It x 232 > Is2in which ≤ It x ≤ rIn <strong>and</strong> x = 1,half-curve 2*:I'Restraint elementThe stability of the protection in the event of external faults, of the energizingof transformers supplied by a machine or of machine starting, is ensured by meansof a tripping restraint when one of the following conditions is met on one of thephases:c detection of an external fault or a starting phase,c detection of CT saturation,c detection of transformer energizing.Detection of an external fault or starting phaseAt the time of starting or an external fault, the through current is much higherthan 1.5 In. As long as the CTs do not saturate, the differential current is low.This transient state is detected by the following characteristic:Id x 2–2Since external faults may be followed by a brief high differential current, a restrainttime over 10 network periods is included so as to ensure protection stabilitywith this type of phenomenon.Detection of CT saturationThe saturation of a CT may cause the appearance of a false differential current<strong>and</strong> inadvertently trip the protection. This type of detection simply analyzes theasymmetry of the signals <strong>and</strong> restrains tripping in the event of CT saturation.Detection of transformer energizing*This type of detection is carried out by ensuring that the harmonic 2 distortionof the differential current is greater than 15%.Id xh2Id xIt x 232 < –(0.25In)2 in which x = 1, 2, 3> 0.15 in which x = 1,High set differential*To avoid unwanted tripping at the time of starting, the protection stability can beimproved by cross-blocking <strong>and</strong> detection of external faults.

IDMT protectionsOperation time depends on the type of protection(phase current, earth fault current, ...).Operation is represented by a characteristic curve:c t = f(I) curve for the phase overcurrent function,c t = f(Io) curve for the earth fault function.The rest of the document is based ont = f(I); the same reasoning may be extended to othervariables Io,…The curve is defined by:c the type (st<strong>and</strong>ard inverse SIT, very inverse VITor LTI, extremely inverse EIT, ultra inverse UIT),c the Is setting current which corresponds to thevertical asympote of the curve,c the T time delay setting which corresponds to theoperation time for I = 10Is.These 3 settings are made in the followingchronological order: type, Is current, T time delay.Changing the T setting by x% changes all theoperation times in the curves by x%.Examples of problems to be solvedProblem n°1Knowing the type of IDMT time,determine the Is <strong>and</strong> T settings.Theoretically, Is is set to the maximum current thatmay be permanent: it is generally the rated currentof the protected equipment (cable, transformer).Time delay T is set to the operation point at 10Ison the curve. This setting is determined taking intoaccount the constraints involved in discriminationwith the upstream <strong>and</strong> downstream protections.The discrimination constraint leads to the definitionof point A on the operation curve (IA, tA),e.g. the point that corresponds to the maximum faultcurrent affecting the downstream protection.Problem n°2Knowing the type of IDMT time, the Is current setting<strong>and</strong> a point K (Ik, tk) on the operation curve,determine the T time delay setting.On the st<strong>and</strong>ard curve of the same type, read theoperation time tsk that corresponds to the relativecurrentI kIs<strong>and</strong> the operation time Ts10 that corresponds to therelative currentIIs =10The time delay setting that should be made in order for the operation curve to passthrough the point K (I k, t k) is:tsT = Ts10 xAnother practical method:The chart below gives the values ofk= tsTs10 as a function of IIsTs10In the column that corresponds to the type of time delay,tread the value k = skin the line that corresponds toTs10The time delay setting to be used so that the operation curve passes throughthe point K (I k, t k) is:ExampleData:T =t kkc type of time delay: st<strong>and</strong>ard inverse time (SIT)c set point: Isc a point K on the operation curve: K (3.2 Is; 4 s)Question: What is the time delay T setting (operation time at 10Is)?Chart reading: inverse columnline IIs= 3.2k = 2.00Answer: The time delay setting is T= 4 2 =2s1 Ik/Is 10Problem n°3Knowing the settings of Is current <strong>and</strong> T time delay for a type of time delay(st<strong>and</strong>ard inverse, very inverse, extremely inverse),find the operation time for a current value of IA.On the st<strong>and</strong>ard curve of the same read the operation time tsA that correspondsto the relative currentIAIs<strong>and</strong> the operation time Ts10 that corresponds to the relative currentIIs = 10The operation time tA for current IA with the Is <strong>and</strong> T settings ist A= t sAxt kt skTTs10tst kt skKI kIsI/IstATtsATs101 IA/Is 10I/Is3/2 Appendix

Processing of thisorder may be time delayed (T4),c detection of a mains supply voltage drop (*) by timedelayedset point 1 of the positive sequenceundervoltage protection (function F381).Load shedding causes:c tripping (motor shutdown),c inhibition of closing while the load shedding orderpersists,c display of the LOAD SHED. message,c activation of remote indication KTS30.The load shedding order is maintained as long as oneof the following three data items is present:c load shedding order on input I12,c mains voltage is less than set point 1 of the positivesequence undervoltage protection (*),c mains voltage is less than set point 2 of the positivesequence undervoltage protection. Set point 2 is alsoused in the restart function (*).In all cases, when the device is drawn out, closing dueto the presence of a load shedding order is inhibited.CommissioningCommissioning involves the 2 methods of activating load shedding:c load shedding triggered by an external order: for this type of use, input I12must be connected <strong>and</strong> time delay T4 must be set.This setting is made:v using the pocket terminal (timer option in the program logic menu),v via the communication link.Default setting: 200 ms.c load shedding triggered by a mains voltage drop (*): for this type of use, timedelayedset point 1 of the positive sequence undervoltage protection must be set(function F381).This setting is made:v using the pocket terminal (F381 P SEQ U/V1 option in the protection menu),v via the communication link.When set point 1 is set the 999 kV, the load shedding operating mode is inhibited.Set point 2 is adjusted in relation to the restart function.(*) Operation is possible with <strong>Sepam</strong> 2000 which include positive sequence undervoltageprotection.Control <strong>and</strong> monitoring functions1/21

It enables staggered restart of process motorswhen the voltage sag that triggers load shedding is ofshort duration.OperationAfter tripping caused by a voltage drop in the mainspower supply, detected by set point 1 of the positivesequence overcurrent protection, 2 situations mayoccur:c the duration of the voltage drop is greater than timedelay T8; tripping is final. External action is required forrestart,c the duration of the voltage drop is less than timedelay T8; a restart order is given. Time delay T9enables motor restart orders to be staggered in orderto avoid overloading the network.Restart enabling is detected after set point 2 of theundervoltage protection (function F382) drops out.This set point enables the return of voltage to bedetected regardless of the load shedding set point(typical setting: 85% Un).The restart order transmitted by this function fits into the open / close <strong>control</strong>scheme.For circuit breaker <strong>control</strong> schemes, a 200 ms pulse is obtained on the closing coilby using time delay T6.For contactors, the pulse on the closing coil is calibrated using time delay T2.Please noteThis function may not be activated with the <strong>control</strong> scheme for latched ordercontactors (see open / close <strong>control</strong> function).CommissioningThe restart function is available on <strong>Sepam</strong>s that include positive sequenceundervoltage protection.

RecloserApplicationDesigned essentially for overhead lines, this function isused to eliminate transient <strong>and</strong> semi-permanent faults,thereby limiting interruptions of user service as muchas possible. It consists of resupplying the circuit thathas been interrupted by protection tripping after a timedelay required to restore isolation with the power off.Main characteristicsc Local or remote start-up via the communication link.c Recloser inhibition via a logic input.c The number of reclosing cycles may be setfrom 1 to 4.This set up may be entered locally or remotely via thecommunication link,c Each cycle is associated with an adjustable isolationperiod.c Tripping associated with each cycle may be assignedby the set up operation to the instantaneous or timedelayedoutputs of the phase overcurrent or earth faultprotections.c The disengagement <strong>and</strong> inhibition time delays areadjustable <strong>and</strong> independent.OperationRecloser initialization:The recloser is ready to operate when all the following conditions are met:c recloser in service, in local mode (KP6) or remote mode (KTC40),c circuit breaker in service <strong>and</strong> closed,c T15 inhibition time delay not running,c none of the recloser inhibition conditions is true (see below).Cycles:If the recloser is in service, ready to operate,<strong>and</strong> a fault appears, 2 situations may occur:c fault not cleared:v after the instantaneous or time-delayed protection has tripped, the isolation timedelay associated withthe first active cycle starts up. When it runs out, a closing order is given <strong>and</strong> thisorder starts up the disengagement time delay. If the protection detects the faultbefore the end of the time delay, a tripping orderis given <strong>and</strong> the next reclosing cycle is activated,v if the fault persists after all the active cycles have taken place, a permanenttripping order is given, the message DEFINITIVE appears on the display unit <strong>and</strong>closing is inhibited until the user has acknowledged the fault.c fault cleared:v if, after a reclosing order, the fault does not appear after the disengaging timedelay has expired, the recloser initializes <strong>and</strong> the message SUCCESSFULappears on the display unit,v if the fault appears after the disengagement time delay, a complete reclosing cycleis started up again.Closing on fault:If the circuit breaker is closed when the fault occurs, or if the fault appears before theend of the inihition time delay, the <strong>Sepam</strong> gives a permanent tripping order(protection time-delayed contact), <strong>and</strong> SEQ OVER appears on the display unit.Recloser inhibition conditions:The recloser is inhibited when one of the following conditions appears:c receipt of an opening order by input I13 or by the telecommunication link,c receipt of a closing order by input I14 or by the telecommunication link,c recloser disabled by KP6 (locally) or by KTC41 (remotely),c receipt of an inhibition order on input I12,c appearance of a fault related to the switchgear.Inhibition lasts until one of the conditions is true.If it appears during a reclosing cycle, 3 situations may occur:c the circuit breaker is closed <strong>and</strong> the fault is cleared: the circuit breaker remainsclosed,c the circuit breaker is closed <strong>and</strong> a protection again detects the presenceof the fault: tripping is permanent,c the circuit breaker is open: it remains pemanently open with inhibition of closinguntil the fault has been acknowledged (reset).Case of switchgear-related faults3 types of faults may cause inhibition of closing:c "pole pressure" fault on input I16 (display message: PRESSURE),c fault linked to trip circuit supervision or position matching supervision(display message: ? CONTROL ?),c fault linked to the failure to execute an open or close comm<strong>and</strong>(display message: ?

Synchronism may be carriedout by two measurement systems which may be adjusted in the synchronismprotection <strong>and</strong> checking function:c measurement of gaps in voltage (dUs), frequency (dFs) <strong>and</strong> phase angle (dPhis),c fulfilment of the conditions of the four voltage absent modes (mode 1, 2, 3 or 4)selected (see protection functions documentation).1/32 Control <strong>and</strong> monitoring functions


OperationA closing request made locally or remotely by the user is maintained in <strong>Sepam</strong>2000for a time T10 <strong>and</strong> triggers closing of the coupling device when the intendedsynchronism conditions are met.Special features<strong>Sepam</strong> 2000 de-activates the closing request when a fault occurs or when anintentional order interrupts the request.The gap checking function is active by default but may be de-activated forÒgeneratorÓ <strong>Sepam</strong> 2000 by setting the KP34 parameter to 1 or by the remotecommunication impulse contact KTC58 (reactivation is possible by setting KP34back to 0 or via the KTC59 contact).The checking by absent voltage mode is inactive by default but may be activated,only when the gap checking function is activated, by setting the KP35 parameter to 1or via the remote communication impulse contact KTC56 (de-activation is possiblevia the KTC57 contact).The synchro-check activation <strong>and</strong> de-activation functions are interlocked with theposition of the Òlocal/remoteÓ selector switch wired to input I18.Local closing <strong>control</strong> via I14 is prohibited when the selector switch is in the remoteposition.Changeover of the selector switch from the local position to the remote position, for atime of T10, triggers interruption of the request if synchro-check is not activated inremote mode.Monitoring of the voltages at either end of the breaking device is carried out via twoinputs with normally closed contacts which allow LV circuit breaker fault contacts orstriker fuse contacts or voltage transformer drawout contacts to be connected.Annunciation managementSetting of the T8 time delay guarantees a minimum closing time for the O33annunciation output in ÒbusbarÓ <strong>Sepam</strong> 2000.A closing request triggers the appearance on the display unit of the blinkingmessage ÒSYNCHROÓ.For generator <strong>Sepam</strong> 2000, should the closing request fail, the message ÒVOLTAGEGAPÓ is displayed or when the value of the voltage gaps is within the set limit, themessages ÒANGLE GAPÓ <strong>and</strong> ÒFREQ. GAPÓ are displayed.Any interruption in the closing request triggers the appearance of the messageÒSTOP SYNC.Ó, accompanied by the message which goes with the event that hascaused the interruption.A voluntary shutdown via input I13 or via KTC33 during the closing request does notgenerate any messages other than ÒSTOP SYNC.Ó.The ÒTaÓ time delay may be used to anticipate the breaking device closing comm<strong>and</strong>when the networks to be coupled are moving dynamically toward the synchronismconditions.The setting of ÒTaÓ depends on the coupling device closing time <strong>and</strong> thecharacteristics of the networks to be coupled.CommissioningUse the pocket terminal or communication:v set the time delay T10 (the default setting is 200 ms),v set the synchro-check function parameters (F181: Syn.

VT supervisionApplicationThis function is used to supervise the LV circuit ofvoltage transformers <strong>and</strong> correct protection functionaction accordingly:v undervoltage,v remanent undervoltage,v synchro-check.OperationThe LV circuit is protected by a LV circuit breaker or by fuses.The corresponding logic input (for example I22 for a <strong>Sepam</strong> 2000 B07 type) is equalto 0 if the LV circuit breaker is open or if the fuses have blown.In this case :c appearance of a message on the display according to the type of <strong>Sepam</strong> 2000,capacitor, generator or busbar (VT, USYNC1 FAIL, USYNC2 FAIL, BB1 VT or BB2VT).This message is automatically erased as soon as the logic input goes back to 1,c inhibition of tripping by the undervoltage protection,c inhibition of remanent undervoltage data,c interruption of the closing request by the “synchro-check”.CommissioningWire the LV circuit breaker auxiliary position contact (circuit breaker closed:contact closed) or the fuse-melting contact (fuses OK: contact closed)to the corresponding logic input.Control <strong>and</strong> monitoring functions1/45

Remote <strong>control</strong> <strong>and</strong> remote annunciationThe st<strong>and</strong>ard <strong>Sepam</strong> 2000 <strong>control</strong> logic includescommunication tables. In the specific documents foreach application (motors, transformers,...), these tablespresent the assignment of remote <strong>control</strong> <strong>and</strong> remoteannunciation relaycoils.This function data file gives some information on theuse of the tables.Remote annunciationc Control fault: KTS1KTS1 = 1 if trip circuit fault (coil burnt out or wire cut)or position discrepancy fault occurs.c Remote <strong>control</strong> open / close fault: KTS2KTS2 = 1 if an open or close remote <strong>control</strong> order is not executed (discrepancybetween the remote <strong>control</strong> order <strong>and</strong> device position report).Use of this remote annunciation requires time delays T5 <strong>and</strong> T6to be set to 200 ms (with pocket terminal, timer heading in the program menu)or for communication).c Position / remote <strong>control</strong> discrepancy: KTS3KTS3 = 1 if the device's open / closed position does not match the last remote<strong>control</strong> order that was transmitted. In such cases, the device was actuated bycomm<strong>and</strong> that was not transmitted by the communication link (local comm<strong>and</strong>,protection tripping, process comm<strong>and</strong>...). Use of this remote annunciation requirestime delays T5 <strong>and</strong> T6 to be set to 200 ms (rubrique pocket terminal, timer headingin the <strong>control</strong> logic menu) or for communication).c External protection tripping: KTS4KTS4 = 1 if the <strong>Sepam</strong> has received a tripping order on input I15. This order isstored in the <strong>Sepam</strong> (lockout) <strong>and</strong> the user must acknowledge in order to unlockclosing. Input I15 is used to connect the output of a protection relay external to the<strong>Sepam</strong> or to connect an intertripping order.c <strong>Sepam</strong> not reset: KTS5KTS5 = 1 until the <strong>Sepam</strong> 2000 is reset (acknowledgement) after fault tripping orinhibition of closing.c Device closed: KTS10KTS10 = 1 if the breaking device is closed (input I1 at 1).c Device drawn out: KTS11KTS11 = 1 if the breaking device is drawn out (input I17 at 1).c Breaking pole fault: KTS12KTS12 = 1 if there is a "pressure" fault in the breaking device (input I16 at 1).c Earthing switch closed: KTS13KTS13 = 1 if input I11 is at 1.c Remote <strong>control</strong> enable: KTS14KTS14 = 1 if input I18 remote <strong>control</strong> enable is at 1. This enabling relates to theremote <strong>control</strong> closing order (KTC34) <strong>and</strong> acknowledgement order (KTC35). Theremote <strong>control</strong> opening order (KTC33) takes priority, it does not depend on input I18.c KTS15 to 31: assigned to protection functionsEach <strong>Sepam</strong> 2000 protection function output is assigned a remote annunciation(latching outputs).c Transmit "blocking input": KTS32KTS32 = 1 if the <strong>Sepam</strong> 2000 send a blocking input (output O14 activated).c Disturbance recording inhibition: KTS51.c Remote setting inhibition: KTS51.Remote <strong>control</strong> ordersc "Open": KTC33Use of KTC33 may require time delay T5 to be set to 200 ms (see open / close<strong>control</strong> function data sheet). KTC33 does not depend on the status of I18 remote<strong>control</strong> enable.c "Close": KTC34Use of KTC34 may require time delay T6 to be set to 200 ms (see open / close<strong>control</strong> function data sheet).KTC34 is processed if input I18 remote <strong>control</strong> enable is at 1.c Acknowledgement (reset): KTC35KTC35 plays the same role as the Reset key on the front of the <strong>Sepam</strong> 2000,KTC35 is processed if input I18 remote <strong>control</strong> enable is at 1.c Peak dem<strong>and</strong> phase current zero reset: KTC36 (equivalent to the Clear key).c Peak dem<strong>and</strong> W <strong>and</strong> VAr zero reset: KTC37 (equivalent to the Clear key).c Tripping current zero reset: KTC38 (equivalent to the Clear key).c Emmergency stop: KTC1v KTC1 = 1 activate breaker tripping <strong>control</strong>, group stop <strong>and</strong> desexcitation,v need to be reseted to 0 by the communication,v reseted to 0 in case of DC failure.c Group stop: KTC2v KTC2 = 1 activate breaker tripping <strong>control</strong>, group stop <strong>and</strong> desexcitation,v need to be reseted to 0 by the communication,v reseted to 0 in case of DC failure.2/2 Control <strong>and</strong> monitoring functions

General characteristicsDependabilityThis chapter presents the main definitionsof dependability <strong>and</strong> how it is taken into considerationin <strong>Sepam</strong> 2000, an analysis of the experience gainedfrom feedback on the installed equipment base<strong>and</strong> the maintenance of <strong>Sepam</strong> 2000.DefinitionsThe definitions which follow are the main definitionsof dependability applied to protective devices:c The reliability of a protective device is its capabilityof performing its function (or functions) over a givenperiod of time in the operating conditions specified bythe manufacturer, i.e. mainly the capability of trippingwhen required <strong>and</strong> the capability of not tripping whenunwanted.c The maintainability of a protective device is mainly itscapability of being easily repaired when maintenancepersonnel dispose of the means prescribed by themanufacturer.c The availability of a protective device is its capabilityof being in a state to perform its function (or functions)at a given point in time in the operating conditionsspecified by the manufacturer.These values do not necessarily have the samemeanings, depending on whether they are consideredfrom the viewpoint of the protective device or theelectrical installation.The availability <strong>and</strong> maintainability of the protectivedevice contribute to the safety of people <strong>and</strong>equipment. The reliability of the protective devicecontributes to the uninterrupted availability of thepower supply.Dependability needs:a trade-off betweentwo unwanted eventsThe mission of protection systems used with circuitbreakers is to guarantee the safety of the installationwhile, at the same time, ensuring the best levelof interrupted power supply.For <strong>Sepam</strong> 2000, this mission is conveyed by twoevents, the target occurrence of which should be zero.c First unwanted event:unwanted tripping of the protective device.An uninterrupted power supply is essential for bothindustrialists <strong>and</strong> utilities. Unwanted tripping dueto the protective device is liable to generate substantialfinancial losses. This event can be avoided byimproving the reliability of the protective device.c Second unwanted event:failure of the protective device to trip.The consequences of a fault that is not cleared areliable to be disastrous. For the sake of operatingsafety, the protective equipment must detect powersystem faults selectively <strong>and</strong> as quickly as possible.This event can be avoided by improving theavailability of the protective device.Consideration of dependabilityin <strong>Sepam</strong> 2000By the same token as electromagnetic compatibility, dependability is taken intoconsideration right from the start of the development of <strong>Sepam</strong> 2000.A Preliminary Risk Analysis (PRA) is used to list the unwanted events linked to thedifferent functions performed by <strong>Sepam</strong>. Quantified dependability targets are setin accordance with the main unwanted events revealed by the PRA.Specialized dependability assessment <strong>and</strong> modeling techniques are used to interpretthe targets in terms of design requirements.c The predicted reliability analysis determines the failure rate of each <strong>Sepam</strong> 2000component in use-related conditions. Compendiums of reliability data such as theMilitary H<strong>and</strong>book 217 (MIL HDBK 217) <strong>and</strong> the CNET RDF93 are used for this.c The Failure Modes, Effects <strong>and</strong> Criticality Analysis (FMECA) analysis is used toanalyze the effects of a simple component failure on the <strong>Sepam</strong> 2000 functions <strong>and</strong>to list the means available to detect them. The FMECA makes it possible to correctcertain risks of malfunctions <strong>and</strong> specify the self-monitoring functions.c The unwanted events are modeled to calculate the probability of their occurrence<strong>and</strong> to check that the dependability targets are being met.A large share of the functions of digital protective equipment devices are performedby the software. It is therefore essential to master the quality of the software in orderto attain the overall dependability targets. Software quality is mastered by theimplementation of a rigorous development method.This method is derived from the recommendations set by the French (AFCIQ) <strong>and</strong>international (IEEE) quality authorities. It stipulates:c the breakdown of development into a series of phases,c the use of design <strong>and</strong> encoding rules <strong>and</strong> methods aimed at achieving a high levelof software structuring,c the use of software configuration management tools which allow all the softwarecomponent parts to be managed.Self-monitoring functions<strong>and</strong> fail-safe position<strong>Sepam</strong> 2000 <strong>units</strong> are equipped with self-monitoring functions (self-tests),which detect internal failures. The failures are classified in two categories:major failures <strong>and</strong> minor failures.c A major failure affects the system’s common hardware resources(e.g. program memory <strong>and</strong> working memory).<strong>Sepam</strong> 2000 is no longer operational. This type of failure may or may not lead to <strong>MV</strong>fault tripping or unwanted tripping, in which case <strong>Sepam</strong> 2000 must react quickly <strong>and</strong>go into the fail-safe position.The fail-safe position is characterized by:v lockout in neutral position of the Processing Unit,v an indicator lit up on the front of the device,v a message on the display,v the Watchdog relay in fault position (deactivated),v the relay outputs (logic outputs) in the deactivated position,v a break in the relay output supply for <strong>Sepam</strong> S46.c Following a minor failure, <strong>Sepam</strong> 2000 is in downgraded operation.It can continue to carry out all of its protection functions if the functions affectedare peripheral ones (display, communication).This classification of failures makes it possible to obtain a compromise betweenbetween a high level of safety <strong>and</strong> a high level of availability.The self-tests performed in <strong>Sepam</strong> 2000 are summarized in the diagramon the next page.3/14 Installation - Use - General characteristics - Testing

Testing – setting record sheetsCommissioning tests<strong>Sepam</strong> 2000 commissioning does not call forindividual testing of the metering <strong>and</strong> protectionfunctions.<strong>Sepam</strong> 2000 has been designed <strong>and</strong> developed toensure all of the functions:c protection,c metering,c program logic.Each of the functions has been factory-tested inits entirety. In addition, <strong>Sepam</strong> 2000 has a highperforming self-testing system which continuallychecks function integrity, (e.g. no settings outsidethe tolerance range, etc.).The product is ready to use <strong>and</strong> commissioninghas been simplified accordingly.Simple testing of one function ensures the correctoperation of the whole group of functions,provided that the product is installed correctly.It is therefore sufficient to check the <strong>Sepam</strong> 2000installation.Checking relates to:c parameter setting,c connection to current, voltage <strong>and</strong> temperaturesensors,c connection of switchgear <strong>control</strong> <strong>and</strong> annunciation.4/2 Installation - Use - General characteristics - Testing

General characteristicsDependabilityThis chapter presents the main definitionsof dependability <strong>and</strong> how it is taken into considerationin <strong>Sepam</strong> 2000, an analysis of the experience gainedfrom feedback on the installed equipment base<strong>and</strong> the maintenance of <strong>Sepam</strong> 2000.DefinitionsThe definitions which follow are the main definitionsof dependability applied to protective devices:c The reliability of a protective device is its capabilityof performing its function (or functions) over a givenperiod of time in the operating conditions specified bythe manufacturer, i.e. mainly the capability of trippingwhen required <strong>and</strong> the capability of not tripping whenunwanted.c The maintainability of a protective device is mainlyits capability of being easily repaired whenmaintenance personnel dispose of the meansprescribed by the manufacturer.c The availability of a protective device is itscapability of being in a state to perform its function (orfunctions) at a given point in time in the operatingconditions specified by the manufacturer.These values do not necessarily have the samemeanings, depending on whether they are consideredfrom the viewpoint of the protective device or theelectrical installation.The availability <strong>and</strong> maintainability of the protectivedevice contribute to the safety of people <strong>and</strong>equipment. The reliability of the protective devicecontributes to the uninterrupted availability of thepower supply.Dependability needs:a trade-off betweentwo unwanted eventsThe mission of protection systems used with circuitbreakers is to guarantee the safety of the installationwhile, at the same time, ensuring the best levelof interrupted power supply.For <strong>Sepam</strong> 2000, this mission is conveyed by twoevents, the target occurrence of which should bezero.c First unwanted event:unwanted tripping of the protective device.An uninterrupted power supply is essential for bothindustrialists <strong>and</strong> utilities. Unwanted tripping dueto the protective device is liable to generatesubstantial financial losses. This event can beavoided by improving the reliability of the protectivedevice.c Second unwanted event:failure of the protective device to trip.The consequences of a fault that is not cleared areliable to be disastrous. For the sake of operatingsafety, the protective equipment must detect powersystem faults selectively <strong>and</strong> as quickly as possible.This event can be avoided by improving theavailability of the protective device.Consideration of dependabilityin <strong>Sepam</strong> 2000By the same token as electromagnetic compatibility, dependability is taken intoconsideration right from the start of the development of <strong>Sepam</strong> 2000.A Preliminary Risk Analysis (PRA) is used to list the unwanted events linked to thedifferent functions performed by <strong>Sepam</strong>. Quantified dependability targets are setin accordance with the main unwanted events revealed by the PRA.Specialized dependability assessment <strong>and</strong> modeling techniques are used tointerpret the targets in terms of design requirements.c The predicted reliability analysis determines the failure rate of each <strong>Sepam</strong> 2000component in use-related conditions. Compendiums of reliability data such as theMilitary H<strong>and</strong>book 217 (MIL HDBK 217) <strong>and</strong> the CNET RDF93 are used for this.c The Failure Modes, Effects <strong>and</strong> Criticality Analysis (FMECA) analysis is used toanalyze the effects of a simple component failure on the <strong>Sepam</strong> 2000 functions<strong>and</strong> to list the means available to detect them. The FMECA makes it possible tocorrect certain risks of malfunctions <strong>and</strong> specify the self-monitoring functions.c The unwanted events are modeled to calculate the probability of their occurrence<strong>and</strong> to check that the dependability targets are being met.A large share of the functions of digital protective equipment devices areperformed by the software. It is therefore essential to master the quality of thesoftware in order to attain the overall dependability targets. Software quality ismastered by the implementation of a rigorous development method.This method is derived from the recommendations set by the French (AFCIQ) <strong>and</strong>international (IEEE) quality authorities. It stipulates:c the breakdown of development into a series of phases,c the use of design <strong>and</strong> encoding rules <strong>and</strong> methods aimed at achieving a highlevel of software structuring,c the use of software configuration management tools which allow all the softwarecomponent parts to be managed.Self-monitoring functions<strong>and</strong> fail-safe position<strong>Sepam</strong> 2000 <strong>units</strong> are equipped with self-monitoring functions (self-tests),which detect internal failures. The failures are classified in two categories:major failures <strong>and</strong> minor failures.c A major failure affects the system’s common hardware resources(e.g. program memory <strong>and</strong> working memory).<strong>Sepam</strong> 2000 is no longer operational. This type of failure may or may not lead to<strong>MV</strong> fault tripping or unwanted tripping, in which case <strong>Sepam</strong> 2000 must reactquickly <strong>and</strong> go into the fail-safe position.The fail-safe position is characterized by:v lockout in neutral position of the Processing Unit,v an indicator lit up on the front of the device,v a message on the display,v the Watchdog relay in fault position (deactivated),v the relay outputs (logic outputs) in the deactivated position,v a break in the relay output supply for <strong>Sepam</strong> S46.c Following a minor failure, <strong>Sepam</strong> 2000 is in downgraded operation.It can continue to carry out all of its protection functions if the functions affectedare peripheral ones (display, communication).This classification of failures makes it possible to obtain a compromise betweenbetween a high level of safety <strong>and</strong> a high level of availability.The self-tests performed in <strong>Sepam</strong> 2000 are summarized in the diagramon the next page.3/4D21 - D22 - D31 - Installation - Use - Commissioning

ImplementationSetting the communicationparametersBefore a <strong>Sepam</strong> 2000 equipped with the Jbuscommunication system is put into service,3 parameters need to be set. These parametersare accessed in the setting terminal “Status” menu.The user presses the “code” key on the settingterminal, enters the password <strong>and</strong> can then modifythe communication parameters.selectiontransmission rate9600 bauds by defaultpress + or - for setting from 300 to 38400 baudsslave n° assigned to the <strong>Sepam</strong> 2000n° 001 by defaultenter directly for setting from 1 to 255parity: no parity, even parity, odd parityeven parity by defaultpress + or -These 3 parameters are saved in the event of a power failure.The Jbus slave number should be assigned before the <strong>Sepam</strong> 2000 is connectedto the communication network.The Jbus slave number is factory-set to 1 on all <strong>Sepam</strong> 2000s.The user sets the communication parameters before connecting the <strong>Sepam</strong> 2000to the communication network.The communication parameters may be changed while the <strong>Sepam</strong> 2000 is operatingwithout disturbing operation.<strong>Sepam</strong> 2000 ignores the first frame received after it is energizedor after the communication parameters are changed via the setting terminal.CE40Bindicatorsredgreencommunicationconnector(item 1B)Operating modes<strong>Sepam</strong> 2000s have 2 indicators on the back, near the communication connector.They provide help for commissioning <strong>and</strong> diagnosis:c green light:The green indicator is activated by variations of the electrical signal on the RS 485network. When the master communicates with <strong>Sepam</strong> 2000, (in transmission orreceiving mode), the green indicator on each <strong>Sepam</strong> 2000 in the RS 485 networkblinks,c red light:the red light goes on when the <strong>Sepam</strong> 2000 communication coupleris in the initialization phase after being energized (initialization status)or after a communication coupler fault has occurred (fault status).The red light stays on for 5 to 6 seconds after the power is switched on, this beingthe duration of the <strong>Sepam</strong> 2000 communication coupler initialization phase.ABack of <strong>Sepam</strong> 2000 with communication option.The communication coupler may be in one of the four following states:c normal:the <strong>Sepam</strong> 2000 CPU <strong>and</strong> the communication coupler are functioning normally:the red lights on the front <strong>and</strong> back (item 1B) of <strong>Sepam</strong> 2000 are off; the green lighton the back is blinking,c downgraded: <strong>Sepam</strong> 2000 is experiencing a fault: the red light on the front is on.There is a break in the dialogue between the <strong>Sepam</strong> 2000 CPU <strong>and</strong> itscommunication coupler, but the coupler is working.All Jbus requests are ignored <strong>and</strong> give rise to the exception reply “<strong>Sepam</strong> 2000 notready” (the red light on the back is off),c initialization:the coupler is in the process of initializing after energizing or after it has been in faultstatus; the red light on the back stays on for 5 to 6 seconds,c fault:the communication coupler has detected an internal communication failure <strong>and</strong>is experiencing a fault, but <strong>Sepam</strong> 2000 is functioning correctly.The coupler is no longer communicating <strong>and</strong> the red communication coupler lightis on or blinking.Jbus/Modbus communication3


Implementation (cont’d)Testing the linkc After cabling, check the indications given bythe green <strong>and</strong> red lights on the back of <strong>Sepam</strong> 2000.c Carry out reading <strong>and</strong> writing cycles using the testzone <strong>and</strong> the Jbus echo mode.c If possible, use <strong>control</strong> logic latched remote <strong>control</strong>bits (KTC1 to KTC32) which the master can read<strong>and</strong> write. The status of these bits may also be readon the setting terminal.The following Jbus frames, transmitted or receivedby a master are given for test purposes whenthe communication option is implemented.Example :Test zonereadingtransmission 01 03 0C00 0002 (C75B) crc,receipt 01 03 04 0000 0000 (FA33) crc.writingtransmission 01 10 0C00 0001 02 1234 (6727) crc,receipt 01 10 0C00 0001 (0299) crc.readingtransmission 01 03 0C00 0001 (875A) crc,receipt 01 03 02 1234 (B533) crc.Jbus echo mode (see function 8 of Jbus protocol)transmissionreceipt01 08 0000 1234 (ED7C) crc,01 08 0000 1234 (ED7C)crcThe CRC transmitted by <strong>Sepam</strong> 2000 is recalculated,which makes it possible to test the calculationof the CRC transmitted by the Jbus master:c if <strong>Sepam</strong> 2000 replies, the CRC received is correct,c if <strong>Sepam</strong> 2000 does not replay, the CRC receivedis not correct.MalfunctionsIn case of problems, it is advisable to connect the <strong>Sepam</strong> 2000s one by oneto the RS 485 network.The display of the Jbus diagnosis counters on the setting terminal makes it possibleto check Jbus exchanges(please refer to the section on “diagnosis counters”).Red light off <strong>and</strong> green light blinking (normal operating situation)The communication coupler is functioning normally but the contents of the messagesmay be false.SolutionCheck the Jbus slave number, the rate <strong>and</strong> the format using the setting terminal<strong>and</strong> at the master level. Ensure that the master is transmitting framesto the <strong>Sepam</strong> 2000 concerned via the RS 232 - RS 485 converter (when applicable).Red light on (steady or blinking) <strong>and</strong> green light blinking or offIf, a few seconds after the <strong>Sepam</strong> 2000 is energized, the red signal lamp is still lit up,the communication coupler is experiencing a fault.SolutionSwitch off <strong>Sepam</strong> 2000 <strong>and</strong> then switch it on again. If the fault persists,a maintenance operation is required.Red light off <strong>and</strong> green light offThe communication coupler is functioning normally but the RS 485 link cablingis faulty.Solutionc Check the cabling on the CCA 619 connector, the CCA branching cable,the CCA 609 connection box <strong>and</strong> the RS 485 network cable.Ensure that the master is transmitting frames to the <strong>Sepam</strong> 2000 concerned viathe RS 232 - RS 485 converter (when applicable).c Check the cabling of each CCA 609;incoming L+ on terminal 1 <strong>and</strong> outgoing L+ on terminal 3;incoming L- on terminal 2 <strong>and</strong> outgoing L- on terminal 4.c Check impedance matching at either end as well as polarization of the RS 485network.<strong>Sepam</strong> 2000 is not communicating correctly with the communication networkSolutionc Check polarization, which should be in one location only, <strong>and</strong> impedancematching, which should be at the ends of the RS 485 network.c Check that you are using the recommended cable, with the characteristicsdescribed in this document.c Check that the ACE 909 converter being used is connected <strong>and</strong> parameterizedcorrectly.Version readoutUsed to display the communication version number on the TSM 2001pocket terminal or with the SFT 2801 PC software program:c “About <strong>Sepam</strong>” menu,c “Communication” heading.Example: Jbus: V3.1<strong>Sepam</strong> 2000 S26, S36 <strong>and</strong> S46 require a Jbus 3.1 or higher versioncommunication coupler.4 Jbus/Modbus communication


Use of remote <strong>control</strong> bitsThe remote <strong>control</strong> bits (KTC) are <strong>control</strong> logic bitswhich may be set to 1 by Jbus communication.They allow <strong>Sepam</strong> 2000 to be remote <strong>control</strong>ledby Jbus communication.To use the remote <strong>control</strong> bits, they must be cabledin the <strong>control</strong> logic scheme. They may be accessed viaJbus communication.Bits KTC 1 to KTC 32 are latched orders (KTCM):they remain in the status in which they are writtenby the master.The operating principle is similar to that of a manualselector switch. The status of bits KTC 1 to KTC 32may be read by Jbus communication <strong>and</strong> usingthe TSM 2001 pocket terminal.The KTC 33 to KTC 96 bits are “impulse” comm<strong>and</strong>s(KTCI) or automatic reset comm<strong>and</strong>s. <strong>Sepam</strong> 2000<strong>control</strong> logic automatically resets them to 0 whenthey have been acknowledged by <strong>Sepam</strong> 2000.The operating principle is similar to that ofa push-button.The KTC bits are reset to zero each time <strong>Sepam</strong> 2000or the communication coupler is started up again.The KTC bits are not stored in the event of a <strong>Sepam</strong>2000 power failure.40 ms must elapse between two consecutivetransmissions of KTCI messages by the master;27 ms must elapse between two consecutivetransmissions of KTCMs.Use of remoteannunciation bitsThe KTS remote annunciation bits are <strong>control</strong> logic bitsrepresented in the form of relay coils, which may beread by Jbus communication. They are implementedin the programmable <strong>control</strong> logic <strong>and</strong> may beaccessed in reading mode by Jbus communication.Diagnosis countersThe following diagnosis counters are managed by <strong>Sepam</strong> 2000:c CPT1, first word: number frames received OK, whether or not the slaveis concerned,c CPT2, second word: number of frames received with a CRC error, or framesreceived with more than 255 bytes <strong>and</strong> not interpreted, or frames received withat least one character that has a parity error, “overrun, “framing”, “break” on the line.Incorrect causes incrementation of CPT2.c CPT3, third word: number of exception replies generated (even if not transmitted,as a result of a broadcast request),c CPT4, fourth word: number of frames specifically addressed to the station(excluding broadcasting),c CPT5, fifth word: number of broadcast frames received with no errors,c CPT6, sixth word: not significant,c CPT7, seventh word: number of “<strong>Sepam</strong> 2000 not ready” replies generated,c CPT8, eighth word: number of frames received with at least one character that hasa parity error, “overrun”, “framing”, “break” on the line,;c CPT9, ninth word: number of correct requests received <strong>and</strong> correctly executed.The counters are accessed using the special reading function(see function 11 of Jbus protocol in appendix).When the value of a counter is equal to FFFFh (65535), it automatically switchesto 0000h (0).After a mains outage or a communication parameter change made using thesetting terminal, the diagnosis counters are initialized to zero.Jbus diagnosis counters CPT2 <strong>and</strong> CPT9 are also accessed using the settingterminal Status-Communication menu (by pressing the “▼” key).Setting the parameters on the masterIn order to set the parameters on the master,it is necessary to have the following information:c list of functions included in the <strong>Sepam</strong> 2000:each <strong>Sepam</strong> 2000 contains a varying number of functions.Only the data for the functions included in the cartridge will be refreshed. The otherdata remain at zero,c cabling of:v logical inputs <strong>and</strong> output relays,v remote <strong>control</strong>led internal bits <strong>and</strong> remote annunciation internal bits(the user should refer to the <strong>Sepam</strong> 2000 <strong>control</strong> logic scheme).c data addresses <strong>and</strong> formats:the addresses <strong>and</strong> formats are listed in the chapter entitled“data addresses <strong>and</strong> encoding”. They are the same for all <strong>Sepam</strong> 2000 models.Jbus/Modbus communication5


Data addresses <strong>and</strong> encodingPresentationData which are similar from the application viewpointare grouped together in adjacent address zones:c the synchronization zone is a table which containsthe absolute date <strong>and</strong> time for time tagging of events,c the identification zone contains system typeinformation pertaining to the identificationof the <strong>Sepam</strong> 2000 equipment,c the events zone is a table which containsa maximum of 4 time tagged events available via Jbuscommunication,c the automation zone contains the <strong>Sepam</strong> 2000logical data <strong>and</strong> PLC event counters,c the test zone is a 16-word zone that is accessiblevia communication by all the Jbus functions, in bothreading <strong>and</strong> writing modes, to facilitate communicationtesting at the time of commissioning. The Jbus mastercan write or read any value without disturbing <strong>Sepam</strong>2000 operation,c the measurements x 1 zone contains the analog measurements,c the measurements x 10 zone contains the same analog dataas the measurements x 1 zone, but in a different format: the unit order is multipliedby 10. This zone is used for applications in which the data in the measurements x 1zone are liable to exceed the maximum value possible,c the measurement (32 bits) zone contains certain measurements of themeasurements x 1 zone expressed in 32 bits,c the <strong>Sepam</strong> 2000 S46 measurement zone contains the measurements whichare specific to this type of <strong>Sepam</strong> 2000.These 4 analog measurement zones are refreshed simultaneously.c The compact zone contains the characteristic data most often used in the mimicdiagrams. They are grouped together to provide quick access via Jbuscommunication.c The configuration zone contains information pertaining to the hardware <strong>and</strong>software configurations; it allows precise identification of the <strong>Sepam</strong> 2000 model.The data addresses are independent of the <strong>Sepam</strong> 2000 model.<strong>Sepam</strong> 2000 sets data to 0 for the functions which are not available.In the tables blow:The first column gives the name of the <strong>Sepam</strong> 2000 information; the word address<strong>and</strong> bit address columns indicate the Jbus address of the information.The access column indicates read or write mode access to read or write data.The “format” <strong>and</strong> “unit” columns indicate the data encoding. The reader should referto the section entitled “Jbus data encoding” in the appendix which describesJbus protocol for a more detailed explanation of the meaning of each of the columnsin the table.Synchronization zoneThe synchronization zone is a table which contains the absolute date <strong>and</strong> timefor the time tagging function.

The time taggingfunction assigns a date <strong>and</strong> precise time to statuschanges so that they can be accurately classifiedwith respect to time.Time tagged data can be processed in the <strong>control</strong>room by the remote monitoring <strong>and</strong> <strong>control</strong> systemvia Jbus communication protocol for data logging<strong>and</strong> chronological reports.<strong>Sepam</strong> 2000 time tags the following data:c logical inputs,c internal remote annunciation bits,c information pertaining to <strong>Sepam</strong> 2000 equipment(see <strong>Sepam</strong> check-word at Jbus address 0C8Fh),c oscillating status of logical inputs <strong>and</strong> KTS bits inorder to avoid saturation of the monitoring <strong>and</strong> <strong>control</strong>system in the event of abnormally frequent statuschanges.At the time of commissioning, the user enablesthe logical inputs <strong>and</strong> the KTS that he wishes to timetag in <strong>Sepam</strong> 2000 using the setting terminal.Time tagging of these events is disabled by default.Chronological sorting of the time tagged events isperformed by the remote monitoring <strong>and</strong> <strong>control</strong>system.Time tagging<strong>Sepam</strong> 2000 time tagging uses absolute time (see section on date <strong>and</strong> time). Whenan event is detected, it is tagged with the absolute time given by <strong>Sepam</strong> 2000’sinternal clock.All the <strong>Sepam</strong> 2000 internal clocks must be synchronized so as to avoid drifts <strong>and</strong> toallow inter-<strong>Sepam</strong> 2000 chronological sorting.<strong>Sepam</strong> 2000 has two mechanisms for managing its internal clock:c time setting:for initializing or modifying the absolute time. A special Jbus message, called “timemessage”, is used to time-set each <strong>Sepam</strong> 2000,c synchronization:to avoid <strong>Sepam</strong> 2000 internal clock drifts <strong>and</strong> ensure inter-<strong>Sepam</strong> 2000synchronization.Internal clocks can be synchronized according to two principles:c internal synchronization:via the Jbus communication network without any additional cabling,c external synchronization:via a logical input with additional cabling.At the time of commissioning, the user sets the synchronization mode parameterusing the setting terminal.Jbus communication<strong>Sepam</strong> 2000 is always the slave with respect to the Jbus master, which means thatthe master station reads the events that are stored in <strong>Sepam</strong> 2000.Time tagged events are transferred between <strong>Sepam</strong> 2000 <strong>and</strong> the master by 4-eventblocks.A special acknowledgment procedure is used for data exchanges.Example of architecture“internal synchronization via the communication network” architecture.master computer<strong>Sepam</strong> 2000Jbus/Modbusnetwork<strong>Sepam</strong> 2000Architecture for “internal synchronization via the communication network”Jbus/Modbus communication19


Time tagging of events (cont’d)Other processing operationsFiltering of oscillating dataAs protection against abnormally frequent statuschanges, <strong>Sepam</strong> 2000 filters oscillating data in orderto avoid saturation of the time tagging communicationfunction. A data item is declared to be oscillating whenit changes status more than 10 +3 times in 2 seconds.Once this occurs, no further status change eventsare generated. A time tagged event “appearanceof oscillating channel” is transmitted. The data itembecomes non-oscillating again when it remains stablefor at least 10 seconds. When this occurs, a timetagged event: “disappearance of oscillating channel”is transmitted. In order to guarantee data consistencyin the monitoring <strong>and</strong> <strong>control</strong> system, a “theoretical”status change is generated, with the same date<strong>and</strong> time, to indicate the stabilized statusof the channel which has ceased to oscillate,whatever its previous status.Data synthesisA synthesis of <strong>Sepam</strong> 2000 data is produced by meansof the <strong>Sepam</strong> status check-word. Status changes ofcertain bits in the words are time tagged. The meaningof each of the bits in the <strong>Sepam</strong> 2000 check-wordis given in the chapter entitled “data addresses<strong>and</strong> encoding” (see format X).The time tagging function processes the followingstatus changes:c presence of a partial fault in <strong>Sepam</strong> 2000,c presence of a major fault in <strong>Sepam</strong> 2000,c setting terminal: in parameter setting mode / inreading mode,c <strong>Sepam</strong> 2000: incorrect time / correct time,c <strong>Sepam</strong> 2000: non-synchronous. / synchronous,c <strong>Sepam</strong> 2000: in data loss status / not in data lossstatus (refer to t he next section entitled “descriptionof event coding”.Installation of the time tagging functionEach time the communication system is initialized(energizing of <strong>Sepam</strong> 2000),the events are generated in the following order:c appearance of “data loss”,c appearance of “incorrect time”,c appearance of “non-synchronous”,c disappearance of “data loss”.The function is initialized with the current valuesof the KTS <strong>and</strong> logical input status without creatingany events related to these data. After the initializationphase, event detection is activated. It can only beinterrupted by saturation of the internal event storagequeue or by the presence of a major fault in<strong>Sepam</strong> 2000.Date <strong>and</strong> timeAn absolute date <strong>and</strong> time are generated internally by <strong>Sepam</strong> 2000, comprising thefollowing information: Year : Month : Day : Hour : minute : millisecond. <strong>Sepam</strong> 2000’sinternal clock is not saved; it needs to be time-set via the Jbus communicationnetwork each time the <strong>Sepam</strong> 2000 is energized.The time that is tagged on events is encoded in 8 bytes as follows:b15 b14 b13 b12 b11 b10 b09 b08 b07 b06 b05 b04 b03 b02 b01 b00 mot0 0 0 0 0 0 0 0 0 Y Y Y Y Y Y Y word 10 0 0 0 M M M M 0 0 0 D D D D D word 20 0 0 H H H H H 0 0 mn mn mn mn mn mn word 3ms ms ms ms ms ms ms ms ms ms ms ms ms ms ms ms word 4Y - 1 byte for years: 0 to 99 years.The remote monitoring <strong>and</strong> <strong>control</strong> system must ensure that the year 00 is greaterthan 99.M - 1 byte for months: varies from 1 to 12.D - 1 byte for days: varies from 1 to 31.H - 1 byte for hours: varies from 0 to 23.mn - 1 byte for minutes: varies from 0 to 59.ms - 2 bytes for milliseconds: varies from 0 to 59999.This information is encoded in binary form. <strong>Sepam</strong> 2000 is time-set via the Jbus“word writing” function (Jbus function n° 16) at Jbus address 0002 with a m<strong>and</strong>atory4-word time message.The bits set to “0” in the description above correspond to format fields whichare not used <strong>and</strong> not generated by <strong>Sepam</strong> 2000.Since these bits can be transmitted to <strong>Sepam</strong> 2000 with r<strong>and</strong>om values,<strong>Sepam</strong> 2000 performs the necessary disabling.<strong>Sepam</strong> 2000 does not check the consistency or validity of the date <strong>and</strong> timereceived.Synchronization clockA synchronization clock is required for setting the date <strong>and</strong> time of <strong>Sepam</strong> 2000.Merlin Gerin has tested the equipment sold by the following suppliers:c SCLE, ref.

Time tagging of events (cont’d)Communicationwith time taggingEvent tableWhen the Jbus master station makes an event readingrequest, <strong>Sepam</strong> 2000 fills in the event table situatedat the Jbus address 0040h. This table containsthe exchange word (address 0040h) <strong>and</strong> a blockof 4 events (address 0041h to 0060h).Exchange wordThe exchange word is used to manage a special protocol to be sure not to loseevents following a Jbus communication problem. The event table is numbered forthis purpose.The exchange word includes two fields:c a most significant byte = exchange number (8 bits): 0..255,b15 b14 b13 b12 b11 b10 b09 b08The events transmitted by <strong>Sepam</strong> 2000 are notsorted chronologically.Structure of the event table:c exchange word 0040h,c event number 10041h ... 0048h,c event number 20049h ... 0050h,c event number 30051h ... 0058h,c event number 40059h ... 0060hThe master necessarily reads a block of 33 wordsstarting at the address 0040h or one wordat the address 0040h.When changes are made to the communicationparameters or the time tagging function, this doesnot modify the contents of the event tableor the exchange word.Exchange number: 0 .. 255Description of the MS byte of the exchange wordThe exchange number contains a numbering byte which identifies the exchanges.The exchange number is initialized to zero when <strong>Sepam</strong> 2000 is energized. When itreaches its maximum value (FFh), it automatically returns to 0.<strong>Sepam</strong> 2000 numbers the exchanges <strong>and</strong> the master acknowledges the numbering.c least significant byte = number of events (8 bits): 0..4.b07 b06 b05 b04 b03 b02 b01 b00Number of events: 0 .. 4Description of least significant byte of the exchange word<strong>Sepam</strong> 2000 indicates the number of significant events in the event table in the leastsignificant byte of the exchange word. Each non-significant event word is initializedto zero.Event table acknowledgmentTo inform <strong>Sepam</strong> 2000 that the block read by the master has been correctlyreceived, the master writes the number of the last exchange made in the “Exchangenumber” field, <strong>and</strong> writes zero in the “Number of events” field of the exchange word.After acknowledgment, the 4 events in the event table are initialized to zero<strong>and</strong> the old, acknowledged events are erased in <strong>Sepam</strong> 2000.Until the exchange word written by the master becomes “X,0”(with X = number of the previous exchange that the master wishes to acknowledge),the exchange word in the table remains at “X, number of previous events”.<strong>Sepam</strong> 2000 only increments the exchange number when new events are present(X+1, number of new events).If the event table is empty, <strong>Sepam</strong> 2000 performs no processing operations whenthe master reads the event table or the exchange word.The data are encoded in binary form.Oscillating dataWhen a data item is declared to be oscillating, its status continues to be updatednormally in the <strong>control</strong> logic zone.If <strong>Sepam</strong> 2000 is in data loss status, i.e. its internal event storage queue is full, theoscillating status information is frozen in the status it was in prior to data loss status.Processing of oscillating data is interrupted when a major fault or data loss occurs.22 Jbus/Modbus communication

Slave number 0 is used for Jbusbroadcasting,c “external” transmission via a logical input mode.The synchronization mode is selected at the timeof commissioning by means of the setting terminal.Jbus/Modbusnetworkmaster computer<strong>Sepam</strong> 2000<strong>Sepam</strong> 2000“Internal synchronization via the communication network”architectureJbus/Modbusnetworkmaster computer<strong>Sepam</strong> 2000<strong>Sepam</strong> 2000clocksynchronizationlinkInternal synchronization via the network modeThe “time message” is used both for time-setting <strong>and</strong> synchronization of<strong>Sepam</strong> 2000. For synchronization, it must be transmitted regularly at brief intervalsin order (between 10 to 60 s) to obtain synchronized time.<strong>Sepam</strong> 2000’s internal clock is reset each time a new time frame is received,<strong>and</strong> synchronization is maintained if the reset amplitude is less than 50 milliseconds.With internal synchronization via the network, accuracy is linked to the Jbus master<strong>and</strong> its mastery of time frame transmission in the Jbus communication network.<strong>Sepam</strong> 2000 is synchronized without delay at the end of the receipt of the Jbusframe.Time changes are made by the transmission to the <strong>Sepam</strong> 2000 of a framecontaining the new date <strong>and</strong> time. <strong>Sepam</strong> 2000 then switches into a transitionalnon-synchronous status.Example of time pulse: 11h 30 mn 10s, ...11h 30mn 20s, ... 11h 30mn 30s... .External synchronization via a logical input mode<strong>Sepam</strong> 2000 can be synchronized externally using a logical input(I11, I21, I413 or I501 according to the <strong>Sepam</strong> 2000 model).Synchronization is carried out on the rising edge of the logical input.<strong>Sepam</strong> 2000 can adapt to all external synchronization time pulse periods from 10to 60 s, by 10 s steps.The shorter the synchronization period, the more accurate time tagging of statuschanges will be. The first time frame is used to initialize <strong>Sepam</strong> 2000 with theabsolute date <strong>and</strong> time; the following frames are used for the detection of any timechanges. The synchronization “logical time pulse” is used to reset <strong>Sepam</strong> 2000’sinternal clock. During the initialization phase, when <strong>Sepam</strong> 2000 is in“non-synchronous” mode, resetting is allowed, within an amplitude of + 4 s.In the initialization phase, the resetting process (switching of <strong>Sepam</strong> 2000 into“synchronous” mode) is based on a measurement of the difference between<strong>Sepam</strong> 2000’s current time <strong>and</strong> the nearest ten second period.This measurement is taken at the time of the receipt of the synchronization timepulse following the initialization time frame. Resetting is allowed if the valueof the difference is less than or equal to 4 seconds, in which case <strong>Sepam</strong> 2000switches to “synchronous” mode. As of that time (the switching to “synchronous”mode), the resetting process is based on the measurement of a different (between<strong>Sepam</strong> 2000’s current time <strong>and</strong> the nearest ten second period at the timeof the receipt of a synchronization time pulse), which is adapted to match the“logical time pulse” period.The synchronization time pulse period is determined automatically by <strong>Sepam</strong>2000 when it is energized: the synchronization time pulse must thereforebe operational before <strong>Sepam</strong> 2000 is energized.To measure the synchronization time pulse period, <strong>Sepam</strong> 2000 uses the first2 synchronization time pulses following the receipt of the initialization frame.The synchronization function only operates after <strong>Sepam</strong> 2000 is time-set, i.e.after the disappearance of the “incorrect time” event.Any time changes greater than + 4 s in amplitude are made by transmitting a newtime frame. The switch from summer time to winter time (<strong>and</strong> vice versa) is madein this way. There is a temporary loss of synchronism when the time is changed.The external synchronization mode requires additional equipment,a “synchronization clock”, to generate a precise periodic synchronization time pulse.If <strong>Sepam</strong> 2000 is in correct time <strong>and</strong> synchronous status when the synchronizationtime pulse is generated, <strong>and</strong> if the difference in synchronism between the nearestten second period <strong>and</strong> the receipt of the synchronization time pulse is greater thanthe synchronism error for 2 consecutive synchronization time pulses, it switches intonon-synchronous status <strong>and</strong> generates the appearance of a “not synchronous”event. Likewise, if <strong>Sepam</strong> 2000 is in “correct time <strong>and</strong> synchronous” status,the failure to receive a synchronization time pulse for 200 seconds generatesthe appearance of a “not synchronous” event.“External synchronization” via a logical input architectureJbus/Modbus communication23

They are indicated for an external synchronization mode with asynchronization “logical signal” with 10-second period synchronization, with accuracyof less than 1 ms.Internal management of eventsc internal storage capacity: 63 time tagged events,c avalanche of events: 63 simultaneous changes.Processing of oscillating datac appearance: if there are 10 ±3 status changes in 2 seconds,c disappearance: if there are 0 status changes during 10 seconds.External synchronizationThe synchronization time pulse should have a duration of more than 40 ms <strong>and</strong> lessthan 4 s.If its duration is more than 1 s, its status may be read on the setting terminal.Setting of time taggingparametersCommissioning of the time tagging function requires prior setting of the followingparameters:c choice of the synchronization mode, internal or external,c validation of events for remote annunciation <strong>and</strong> logical inputs.These settings are accessible via the “time tagging” heading of the setting terminal“Status” menu.The user presses the “code” key on the setting terminal <strong>and</strong> enters the passwordbefore modifying the parameters.Using the ▼ or ▲, keys, <strong>and</strong> the “enter” key:c select the “Status” <strong>and</strong> then “Time tagging” menus,c choose the external synchronization mode <strong>and</strong> validation of events.Time tagging menuChoice of synchronization modec Network (st<strong>and</strong>ard by default),c Logical input I11,c Logical input I21,c Logical input I413,c Logical input I501,according to the <strong>Sepam</strong> 2000 model.The dynamic status of bits b8, b14 <strong>and</strong> b16 of the <strong>Sepam</strong> check-word is displayedin the menu (b8 = C8F7, b14 = C8FD, b15 = C8FE, b16 = C8FF).Validation of eventsDirect input, 0 or 1 for each remote annunciation <strong>and</strong> logical input.c Not validated (by default): 0c Validated: 1.A value of 1 for each remote annunciation <strong>and</strong> logical input indicates that the timetagging operations have been validated for the corresponding resources.A value of 0 disables time tagging processing operations (use keys ▼,▲).Modification of these parameters triggers initialization of the <strong>Sepam</strong> 2000communication function. The parameters are saved in the event of a power failure.24 Jbus/Modbus communication


<strong>Sepam</strong> 2000 internal eventsThe internal events are associated <strong>Sepam</strong> check-wordstatus at the Jbus address 0C8h.Presence of a major fault in <strong>Sepam</strong> 2000Whenever a major fault appears, <strong>Sepam</strong> 2000responds by an exception reply: “<strong>Sepam</strong> 2000not ready”. When the fault disappears, the masterreads the following in the event table:c appearance of “major fault”,c appearance of “data loss”,c disappearance of “major fault”,c disappearance of “data loss”,c appearance / disappearance of “non-synchronous”according to <strong>Sepam</strong> 2000’s synchronism status.Setting terminal: in parameter setting mode (1) /in reading mode (0)The appearance of “terminal in setting mode” eventis generated when a user connects locally to <strong>Sepam</strong>2000 using the setting terminal in parameter settingmode, i.e. after having pressed the “code” key on thesetting terminal <strong>and</strong> entered the password.The complementary event is generated when thesetting terminal is switched back to reading mode.Internal synchronization modeIn this mode, <strong>Sepam</strong> 2000 is in “correct time” <strong>and</strong> “synchronous”status after the receipt of the first “time message” frame.If <strong>Sepam</strong> 2000 is in correct time <strong>and</strong> synchronous status, it switchesto non-synchronous status if the synchronism error is greater than 50 milliseconds.<strong>Sepam</strong> 2000 declares itself “non-synchronous” when the difference betweenthe current <strong>Sepam</strong> 2000 time <strong>and</strong> the time frame received is greater than 50milliseconds for 3 consecutive time frames.When <strong>Sepam</strong> 2000 is in synchronous status, if no “time message” is receivedfor 200 seconds, the appearance of a “non-synchronous” event is generated.<strong>Sepam</strong> 2000 in data loss (1) / no data loss (0) status<strong>Sepam</strong> 2000 has an internal storage queue with a 64-message capacity.In the event of saturation of the queue, i.e. 63 events already present,the “data loss”, event is generated by <strong>Sepam</strong> 2000 in the 64th position<strong>and</strong> detection of events is interrupted.Event detection is only started up again when the internal queue has beencompletely emptied by the master. The system event, disappearance of “data loss”is then generated.The appearance/disappearance of “non-synchronous” is generated accordingto <strong>Sepam</strong> 2000 synchronization status.<strong>Sepam</strong> 2000: incorrect time (1) / correct time (0)The appearance of the “incorrect time” event isgenerated by <strong>Sepam</strong> 2000 each time it is energized<strong>and</strong> after re-initialization of the <strong>Sepam</strong> 2000communication system. <strong>Sepam</strong> 2000 initializes witha default time: 1 June 1993 0 hours 0 minutes 0milliseconds <strong>and</strong> the “incorrect time” status is set.The appearance of the “incorrect time” event indicatesthat time-setting by the master is required.When a time frame is received, <strong>Sepam</strong> 2000 switchesto “correct time” status <strong>and</strong> the “incorrect time” eventdisappears.<strong>Sepam</strong> 2000: non-synchronous (1) /synchronous (0)The date <strong>and</strong> time associated with the status changeswhich follow the appearance of a “non-synchronous”event prevent correct inter-<strong>Sepam</strong> 2000 chronologicalevent sorting. Once <strong>Sepam</strong> 2000 has becomesynchronous again, the disappearanceof “non-synchronous” event is generated.When the disappearance of the “incorrect time” <strong>and</strong>“non-synchronous” events takes place, <strong>Sepam</strong> 2000time tagging enables correct chronological sorting.Jbus/Modbus communication25

Disturbance recordingPresentationThe disturbance recording function is used to recordanalog <strong>and</strong> logical signals during a time interval.<strong>Sepam</strong> 2000 can store two records. Each recordcomprises two files:c configuration file with suffix .CFG,c data file with suffix .DAT.The data of each record may be transferred viathe Jbus link.It is possible to transfer 1 or 2 records to a remotemonitoring <strong>and</strong> <strong>control</strong> system. The record may betransferred as many times as possible,until it is overwritten by a new record.If a record is made by <strong>Sepam</strong> 2000 while the oldestrecord is being transferred, the oldest record is altered.If a Jbus comm<strong>and</strong> (e.g. a remote reading or remotesetting request) is carried out during the transferof a disturbance recording record,the record is not disturbed.Time settingEach record may be dated.Time setting of the <strong>Sepam</strong> 2000 is only carriedout by the remote monitoring <strong>and</strong> <strong>control</strong> system.Time setting is done in the same way as time tagging(see section on synchronization). If no time setting iscarried out, the date <strong>and</strong> time are 1 June 1993 0 hour,each time the <strong>Sepam</strong> 2000 is energized.Transferring recordsThe transferring request is made record by record, i.e.one configuration file <strong>and</strong> one data file per record.The master sends the Jbus comm<strong>and</strong>s in order to:c find out the characteristics of the records storedin an identification zone,c read the contents of the different files,c acknowledge each transfer,c reread the identification zone to ensure that therecord still appears in the list of records available.Reading the identification zoneGiven the volume of data to be transmitted, the master must ensurethat there are data to be recovered <strong>and</strong> prepare the exchanges when necessary.The identification zone, described below, is read by Jbus reading of N words startingat the address D204h:c 2 reserve words forced to 0,c size of record configuration files encoded in 1 word,c size of record data files encoded in 1 word,c number of records encoded in 1 word,c date of the record (most recent) encoded in 4 words (see format below),c date of the record (oldest) encoded in 4 words (see format below),c 25 reserve words.All of these data are consecutive.Reading the contents of the different filesRequest frameThe request is carried out by the master by writing in 4 words, starting at the addressD200h, the date of the record to be transferred (Jbus code 16).It should be noted that requesting a new record amounts to stopping the transferswhich are in progress. This is not the case of an identification zone transfer request.D200hB15 B14 B13 B12 B11 B10 B09 B08 B07 B06 B05 B04 B03 B02 B01 B00OOOmsOOOmsOOOmsO O O O O Y Y Y YO M M M M O O O TH H H H H O O mn mnms ms ms ms ms ms ms ms msY - 1 byte for years: varies from 0 to 99 years.The remote monitoring <strong>and</strong> <strong>control</strong> system must ensure that the year 00 is greaterthan 99.M - 1 byte for months: varies from 1 to 12.D - 1 byte for days: varies from 1 to 31.H - 1 byte for hours: varies from 0 to 23.mn - 1 byte for minutes: varies from 0 to 59.ms - 2 bytes for milliseconds: varies from 0 to 59999.Reply frameReading of each portion of configuration <strong>and</strong> data file records by a Jbus reading(Jbus code 3) 125 words from at D300.YTmnmsYTmnmsYTmnmsYTmnmsD300hB15 B14 B13 B12 B11 B10 B09 B08 B07 B06 B05 B04 B03 B02 B01 B00number of usable bytesexchange numberin the data zone…………data zone…………Reading should always begin with the first word in the address zone(any other address triggers an exception reply «incorrect address»).The configuration <strong>and</strong> data files are read in their entirety in the <strong>Sepam</strong> 2000.They are transferred adjacently.34 Jbus/Modbus communication


If the master requests more exchanges than necessary, the exchange numberremains unchanged <strong>and</strong> the number of usable bytes is forced to 0.To guarantee the data transfers, it is necessary to allow a response time of about500 ms between each reading operation at D300h.The first word transmitted is an exchange word. The exchange word comprisestwo fields:c the most significant byte contains the exchange number.It is incremented by 1 by the <strong>Sepam</strong> 2000 each time a successful transfer takesplace. When it reaches the value FF, it automatically goes back to zero,c the least significant byte contains the number of usable bytes in the data zone.It is initialized to zero after energizing <strong>and</strong> must be different from FFh.The exchange word may also have the following values:c xxyy: the exchange number xx must be different from FFh, the number of usablebytes in the data zone yy must be different from FFh,c 0000h: no «request frame» has been formulated yet, as it is the case, in particular,when the <strong>Sepam</strong> 2000 is switched on. The other words are not significant,c FFFFh: the «request frame» has been processed, but the results in the «replyframe» are not yet available.It is necessary to repeat «reply frame» reading. The other words are not significant.c 00FFh: the communication coupler supports the disturbance recording functionsbut not the program in the <strong>Sepam</strong> 2000 cartridge. The other words are notsignificant. However, if the master requests records from a <strong>Sepam</strong> 2000 which doesnot support the disturbance recording function at the coupler level, the <strong>Sepam</strong> 2000replies by a exception reply in the Jbus sense of the term.The words which follow the exchange word make up the data zone.Since the configuration <strong>and</strong> data files are adjacent, a Jbus frame may containthe end of the configuration file <strong>and</strong> the beginning of the data file of a record.It is up to the remote monitoring <strong>and</strong> <strong>control</strong> system software to reconstruct the filesin accordance with the transmitted number of usable bytes <strong>and</strong> the size of the filesindicated in the identification zone.Acknowledging a transferTo inform the <strong>Sepam</strong> 2000 that a record block that it has just read has been receivedcorrectly, the master must write the number of the last exchange that it has carriedout in the “exchange number” filed <strong>and</strong> set the “number of usable bytes in the datazone” of the exchange word to zero.The <strong>Sepam</strong> 2000 only increments the exchange number if the new acquisition burstsare present.Rereading the identification zoneTo ensure that the record has not been modified, during its transfer by a new record,the master rereads the contents of the identification zone <strong>and</strong> ensures thatthe recovered record date is still present.Jbus/Modbus communication35

<strong>Protection</strong><strong>and</strong> <strong>control</strong><strong>Sepam</strong> range<strong>Sepam</strong> 2000Testing


<strong>Sepam</strong> 2000 testsWhen commissioning <strong>Sepam</strong>, it is not necessaryto test the metering <strong>and</strong> protection functionsindividually.<strong>Sepam</strong> has been designed <strong>and</strong> developed to provide the following functions:c protection,c metering,c program logic.Each of the functions has been fully tested. In addition, <strong>Sepam</strong> 2000 has a highlyefficient self-testing system which continuously checks function integrity (e.g. nosettings outside the tolerance range, etc.).The product is ready to use, which simplifies commissioning.By simply testing a function, the user is assured of overall device operation,provided the device has been correctly installed.It is therefore sufficient to check that <strong>Sepam</strong> has been installed properly.The following are checked:c parameter setting,c current <strong>and</strong> voltage sensor connections,c switchgear <strong>control</strong> <strong>and</strong> annunciation connections.The chapter entitled commissioning tests describes the simple, exhaustivemethod that is applied for checking.Individual testing of each protection <strong>and</strong> <strong>control</strong> function is no longer essential.However, should the testing of a function prove to be necessary, please refer to thesection entitled function tests.2 <strong>Sepam</strong> 2000 - Testing

Measurement <strong>and</strong> testing methodGeneral informationEach protection function may be activated individuallyby disabling the set points of the other functions.Activating <strong>and</strong> de-activating functions does not disturbfunction operation in any way.Most of the tests may be performed using aSingle-Phase injection unit, with the exception ofphase rotation checking.Three-phase injection is recommended for checkingcertain functions, in particular:c earth fault current measured by the sum of the3 CTs,c neutral voltage displacement measured by the sumof the 3 VTs,c positive sequence undervoltage <strong>and</strong> phase rotation,c directional overcurrent.Terminal boxes (type "Entrelec", "Secura", etc…) aregenerally used for testing in LV cubicles, which meansthat it is not necessary to disconnect any existingwiring connections.Checksc prior to energizingCheck:v auxiliary voltages of <strong>Sepam</strong> <strong>and</strong> ESB, ESTOR modules,v coherency between the cartridge <strong>and</strong> <strong>Sepam</strong> labels (model, type),v module insertion <strong>and</strong> presence of DPC straps,v setting of microswitches on the ECM, 3U/Vo <strong>and</strong> ECA modules,v connection of the core balance CT (P1-P2 <strong>and</strong> S1-S2 directions),v wiring of currents <strong>and</strong> voltages (rotation <strong>and</strong> matching),v wiring <strong>and</strong> polarization of the required inputs <strong>and</strong> ouputs.c after energizingv set the parameters under the status heading,v set (1) the time delays required by the automation systems (T1, T2 etc…),the parameters values (KPxx),v in the case of customized program logic: check that the protection contacts(FXXX/X) to be tested, as well as the output relays associated with the protections,are being used.c prior to injectionv set the values of the protections to be tested,v disable the set points of other protections that are liable to interfere with testing.Please note:Remember to re-activate the protections at the end of testing (protections aregenerally disabled by setting to 999, kA, kV, etc …).c tolerance ranges <strong>and</strong> injection limitsv current:- minimum 1.5% of CT In (150 mA or 750 mA) (2) ,- maximum 3 times steady state In (3 A or 15 A) (2) , 24 times In for 3 s(24 A or 120 A) (2) ,- 50 Hz (±10%);v voltage:- minimum 1.5% of Un (0.86% of Vn) i.e. 1.5 V for 100 V (3) ,- maximum 150% of Un,- 50 Hz (±10%).Remarks:In order to simplify the presentation of examples, injection current values are givenin primary amperes (like <strong>Sepam</strong> 2000 measurements).When the current injection unit is equipped with electronic ON/OFF <strong>control</strong>s,check that current is zero in the automatic OFF position (since the static contactormay allow more than 5% of the current to flow through, depending on the positionof the cursor). When the starts per hour protection is being tested, in particular,the current broken should be less than 5% of Ib.(1)in the case of st<strong>and</strong>ard logic, refer to the <strong>control</strong> <strong>and</strong>monitoring function manuals(2)to the position corresponding to 1 or 5 A according to themicroswitch setting(3)according to SM2001 pocket terminal setting of the value(Uns) of the VT secondary circuitUn : phase-to-phase voltageVn : phase voltageIn : rated current on CT primaryIb : exact load current (manufacturer data)<strong>Sepam</strong> 2000 - Testing1/3
