Which generator operating mode uses an electronic governor for precise speed control?

Which generator operating mode uses an electronic governor for precise speed control?

• A. Base load
• B. Standby
• C. Precise
• D. Prime

Answer: (C)

The key idea is how speed is controlled. An electronic governor provides fast, precise feedback to regulate fuel and keep the generator running at the exact speed needed. In the mode described, that electronic governor is used to achieve tight rpm control despite changing load, which is what “precise” speed control is all about. Other operating modes describe how the generator is used (continuous base load, emergency standby, or variable-load prime) rather than the level of speed precision provided by the governor. They may still use governors, but the term that specifically signals exact speed regulation with an electronic governor is the precise mode.
