    Procedure section of this guide. To Obtain an SEL-300G Relay Instruction Manual To obtain a copy of the SEL-300G Relay Instruction Manual, simply contact the factory using the instructions below. The SEL-300G Relay Instruction Manual contains additional details on relay operation and settings calculations.

  • Page 10: Relay Commissioning Procedure

    Introduction The procedure below is intended to help you enter settings into an SEL-300G and verify that the relay is properly connected. Steps later in the procedure call for operation of the protected generator at no load, light load, and full load to verify ac connections and take measurements for calculation of 100% stator ground fault protection elements.

    Relay Commissioning Procedure Step 1. Ensure that dc power is removed from the SEL-300G dc circuits by opening the appropriate dc breaker or removing dc fuses. Step 2. Verify the accuracy and correctness of the ac and dc connections by performing point-to-point continuity checks on the circuits associated with the SEL-300G Relay.
