Formula
Notes/Description
Amps (System)
L1 + L2 + L3
3
Average of L1, L2, and L3 amp values.
Volts (System )
Sum of three phase to neutral voltages
3
For a Phase to Neutral with WYE
configured meter.
Average of the three phase-to-neutral
voltages.
kW (System)
L1 kW + L2 kW + L3 kW
Sum of L1, L2, and L3 phase watt
values.
kWh (System)
L1 kW + L2 kW + L3 kW
# of samples in an hour
Calculated per waveform sample with
a running total of each waveform kWh
for the integration period.
VAR (System)
L1 kVAR + L2 kVAR + L3 kVAR
VARh (System)
