  35. Trip Bus – Set Relay without Using Logic . . . 16 input OR gate….up to 6 TRIP BUS elements can be configured

  36. 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.

  37. Sources and Transformer Configuration Assumption: Step-up Transformer is -30° lagging (from line side to generator side) Sources to match Typical Wiring Diagram: Transformer Configuration
