▪ The voltage transformer VT is connected to the phase conductors L1 and
L2.
▪ The current transformer CT is looped into the phase conductor L2.
▪ The current I
L2
is ahead of voltage U
L2
-U
L1
by 30°. This corresponds to a
phase shift of -30°.
▪ The voltage drop on a phase conductor is determined by the current I
L2
.
If you use this circuit, set the device as follows:
