Note 1.
When only the auxiliary power supply is applied, a value close to a phase angle of 0° (power factor of 1) is output.
Use a transducer “for unbalanced loads” if there is a possibility for the 3-phase load to become unbalanced.
With transducers for both balanced circuits and unbalanced loads, an error may occur when the 3-phase voltage becomes unbalanced.
Operation will be abnormal when the input is a negative-phase sequence.
For low-voltage circuits, grounding of the secondary sides of the instrument voltage transformer and current transformer is unnecessary.
