🔍 Key Concepts

• Governor action and what happens when a diesel generator overspeeds • How generator speed relates to voltage, frequency, and mechanical stress on rotating parts • Protective trips: low voltage trip, reverse power trip, and what typically causes overheating

💭 Think About

• Think about whether overspeed makes the generator produce more or less voltage and what that would do to a low-voltage trip. • Consider which protective trip is associated with a generator acting like a motor (taking power from the bus instead of giving it). Would overspeed cause that? • Ask yourself which component of a generator is spinning at high RPM and what happens to it if the speed goes well above design limits.

✅ Before You Answer

• Be clear on whether overspeed would normally cause low voltage or high voltage/frequency. • Review what condition causes a reverse power trip (direction of power flow, not speed). • Identify which part of the generator is most vulnerable to centrifugal forces at high RPM and what kind of damage that could cause.
