🔍 Key Concepts

• AC generator shutdown sequence and priorities • Effects of suddenly removing load vs. removing excitation • Relationship between load, field excitation, and voltage regulation

💭 Think About

• In normal operation, what component (load, field, breaker, or regulator mode) should be adjusted first to avoid voltage spikes or system disturbances? • What might happen to the system if you open the generator breaker while it is still carrying substantial load? • How does changing excitation or regulator mode while on load affect voltage and other connected equipment?

✅ Before You Answer

• Identify which step directly affects the connected electrical system and loads the most if done abruptly • Determine which action is normally done only after the generator is nearly unloaded • Verify the typical recommended sequence in generator shutdown: load handling, excitation/voltage control, and isolation from the bus
