Which of the following should be the FIRST step in removing a generator from parallel operation when no longer needed?

🔍 Key Concepts

• Load sharing between generators in parallel • How governor speed settings affect real (kW) load on each generator • Why you must avoid sudden loss of load on the switchboard when removing a generator

💭 Think About

• Before you can safely open a generator’s breaker, what must happen to the load it is carrying? • Which control (governor vs. breaker vs. shutdown) directly changes how much real power a generator in parallel is supplying? • If you reverse the frequency (cycles) relationship between the oncoming and off‑going machines, what does that do to load flow and system stability?

✅ Before You Answer

• Verify which action allows smooth transfer of kW load from the off‑going generator to the one that will remain on line. • Check which step would cause an instantaneous loss of that generator’s load if done first. • Confirm which choice correctly adjusts the speed/load balance between the two generators before any breaker is opened or prime mover is shut down.

Which of the following should be the FIRST step in removing a generator from parallel operation when no longer needed?

Trip the off-going generator off-line by opening its circuit breaker.

Shut down the prime mover driving the off-going generator.

Decrease the governor setting on the 'off going' generator while simultaneously increasing the governor setting on the generator to remain on line.

Decrease the cycles of the generator staying on the line while simultaneously increasing the cycles of the 'off going' generator.
