A synchronous motor working at leading power factor can be used as____________?
Correct answer: B. phase advancer
- A. voltage booster
- B. phase advancer
- C. noise generator
- D. mechanical synchronizer
Explanation
A synchronous motor operating at leading power factor supplies leading reactive power to the system, acting as a phase advancer. This helps improve the power factor of lagging loads.
