Q

By what means is a constant output voltage from an AC generator maintained?

If the question has a related picture, it will appear here.

🔍 Key Concepts

• Relationship between generator field excitation and output voltage • Role of a governing system vs. a voltage control system on an AC generator • Protective devices (like relays) vs. control/adjusting devices

💭 Think About

• Which device or system directly adjusts the generator’s magnetic field strength to keep terminal voltage steady as load changes? • Which option is mainly responsible for keeping frequency and speed constant, not voltage? • Which option is primarily a protective device that acts during abnormal conditions instead of continuously regulating normal output?

✅ Before You Answer

• Identify which choice acts continuously to keep voltage within limits under normal operation • Separate the function of speed/frequency control from voltage control in an AC generator • Confirm which device is typically associated with reverse power flow protection, not normal regulation
