Fig. TN-C system with single-phase three-wire
connection. The null is taken from the voltage
measurement input V3's measured value
and not calculated.
Fig. The values obtained from the voltage
measurement inputs V2 and V3 are taken
to be null and not calculated.
Fig. System with uniform phase loading.
The measured values for the voltage
measurement input V2 are calculated.
