Record Energy Consumption
- Total active energy consumed during the recording
- Max peak active power
- Date and time recorded at the peak of power
- Date of start and stop recording
- Record Time
- Display of the recorded power
Flicker measurement
- Pst = Severity of Flicker short term calculated in an interval of 10 minutes.
- Plt = Severity of Flicker long term calculated from a sequence of 12 values of Pst on an interval of two hours.
Inrush current
- The power quality analyzer HT PQA824 is able to perform measurements and recordings of inrush currents with a minimum resolution of 10ms which is possible to obtain both numerical and graphical representations. The values obtained are:
- 1000 events
- Phase L1, L2, L3 in which the event occurred
- Date / Time at which the event occurred
- Maximum value reached by the current
Fast transients (Spikes)
- The model PQA824 high sampling frequency allows you to perform the detection of fast voltage transients (spikes) with a resolution of at least 5μs (200kHz) and store them all in a full report of:
- Number of stage on which occurred the spike
- Date and time at which it occurred spike
- Type Up or Down
- Speed of the phenomenon Fast or Slow
Easy System Configuration
- 4-wire, 3-wire, single-phase ARON
- STD or FLEX Clamps
- Frequency System
- Interfacing with Voltage transformers (TV) EN50160 Analysis
- Display in graphical and tabular form analysis of the quality of the electricity service in accordance with EN50160.
