The standard full-load power factor ratings for synchronous motors are___________?
Correct answer: C. unity or 0.8 leading
- A. zero or 0.8 leading
- B. unity or 0.8 lagging
- C. unity or 0.8 leading
- D. unity or zero
Explanation
Synchronous motors are commonly rated for unity power factor or 0.8 leading power factor. The leading rating reflects their ability to provide reactive-power compensation.
