If you use this circuit, set the device as follows:
Parameter Option
Voltage-transformer circuit 3 Ph differential voltage
Current-transformer circuit 3 Ph phase current
Phase angle correction 30°
Table 20: Circuit E
Circuit F
▪ 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 U
L1
-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
.
