▪ The voltage transformer VT is connected to the phase conductors L1 and
L2.
▪ The current transformer CT is looped into the phase conductor L1.
▪ The current I
L1
lags behind voltage U

L2
by 30°. This corresponds to a
phase shift of +30° and a correction value of -30°.
▪ The voltage drop on a phase conductor is determined by the current I
L1
.
