Q

By what means is an AC generator prevented from becoming motorized?

🔍 Key Concepts

• AC generator (alternator) operating in parallel with a power system • Difference between protecting against overspeed and protecting against reverse power flow • What happens if a generator starts drawing power instead of supplying it

💭 Think About

• Ask yourself: In what situation would an AC generator start to act like a motor instead of a generator? • Which of these devices specifically monitors the direction of power flow rather than speed, pressure, or engine fuel control? • Which options are more about prime mover protection (engine/turbine) rather than electrical protection of the generator itself?

✅ Before You Answer

• Identify which choice directly relates to electrical power direction (into vs. out of the generator). • Eliminate options that only react to mechanical speed or steam/exhaust pressure without checking power flow. • Confirm that the remaining device would trip the generator off the bus if it begins to consume power.
