▪ The voltage transformer VT is connected to the phase conductor and the
neutral 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:
