Instantaneous measurements
Instantaneous readings include:
-
3-phase voltages (line-to-line, line-to-neutral): per phase and average
-
Line-to-earth voltages per phase and V4, neutral-to-earth voltage
-
3-phase currents: per phase and average
-
I4 and I5 currents, measured
-
Residual current, calculated (I calc res)
-
Active (kW), reactive (kVAR) and apparent (kVA) power: per phase and total
-
Power factor per phase and total
-
System frequency
-
Voltage and current unbalance
-
Phase reversal
