No In-Zone Transformer - GE G30 Instruction Manual

OVERVIEW CHAPTER 8: APPLICATION OF SETTINGS
The GSU is again lagging by –30° (from the line side to the generator side). Loss of excitation and reverse power is to be
assigned to source 1. In this case, the only phase shift that must be accounted for is the phase shift of the transformer.
Winding 2 is therefore shifted by –30°.
