Circuit A
▪ The voltage transformer VT is connected to the phase conductor and neu-
tral conductor.
▪ The current transformer CT is looped into the phase conductor.
▪ The voltage U
L1
and current I
L1
are in phase.
▪ The voltage drop on a phase conductor is determined by the current I
L1
.
If you use this circuit, set the device as follows:
Parameter Option
Voltage-transformer circuit 1 Ph phase voltage
Current-transformer circuit 1 Ph phase current
Phase angle correction 0°
