Before you start
- Qualified electrical personnel must conduct these tests. Lethal voltage may be present at both the generator and voltage regulator terminals.
Procedure
- Disconnect generator output from load; main circuit breaker or fused disconnect open.
- Open input power to the automatic voltage regulator; remove fuse or disconnect and insulate one regulator input power lead.
- Verify all prime mover start-up procedures have been followed.
- If equipped with space heaters, ensure they are de-energized.
- Start the prime mover and adjust for proper speed per generator nameplate.
- Check all line-to-line and line-to-neutral voltages for balance; shut down and reconnect regulator if balanced.
- Start the set; adjust terminal voltage with regulator voltage adjustment and adjust stability if equipped.
- Record no load excitation (DC voltage to exciter stator), terminal voltage and driver speed as benchmark.
- Close the main circuit breaker to the load.
- Monitor generator output current to verify at or below nameplate value.
- Check generator speed (frequency) under load and adjust as necessary.
