Tab. 10-4: Factors for single-side, two-phase, phase-opposition feed in phases B to C, not zero
sequence-filtered.
The connection of the phase currents can be checked using the phase angles
provided as measured operating data by the P631.
If the phase currents are connected correctly and there is an ideal balanced load
on the transformer, the phase angles between the phase currents of any one
transformer end are displayed as follows:
