Trip Bus – Set Relay without Using Logic
. . . 16 input OR gate….up to 6 TRIP BUS elements can be configured
35
Sources and Transformer Configuration
Note CT polarities in Typical Wiring Diagram and connections to G30. These are
necessary to correctly meter forward power. The transformer phase shift setting
must compensate the measured relay currents for both the actual phase shift of
the transformer, and any phase due to the CT polarities and connections.

Sources and Transformer Configuration
Assumption:
Step-up Transformer is -30° lagging (from line side to generator side)
