lists apparent energy raw values (one phase/sum of phases) at varying
percent of nominal phase currents with nominal voltage 240V or 480V for SP2
model.
Maximum Current (register 43…45)
The rms current is averaged over 10 cycles (200 mS in a 50 Hz system, 167 ms in
a 60 Hz system). The maximum average current in each phase, measured during
the recording interval, is kept in registers 43…45.
Minimum Voltage (register 46…48)
The rms voltage for each phase is averaged over 10 cycles. The minimum voltage
value measured during the recording interval is kept in registers 46…48.
Model Configuration (register 49)
