🔍 Key Concepts

• Power factor and how it relates to real power (kW) vs reactive power (kVAR) in AC generators • What governor controls actually regulate in a generator set • What automatic voltage regulators (AVRs) actually control when alternators are operating in parallel

💭 Think About

• When two alternators are in parallel, which control (governor or voltage regulator) is primarily responsible for sharing real power (kW)? • Which control is primarily responsible for sharing reactive power (kVAR) and thus affecting the power factor of each machine? • Look at each choice and ask: is this device normally used to change speed/frequency, voltage, current, or power factor?

✅ Before You Answer

• Verify which system (governor vs AVR) controls speed/frequency and kW load sharing • Verify which system controls terminal voltage and reactive power (kVAR) sharing, which directly affects power factor • Confirm whether current transformers are measuring devices or control devices in this context
