The primary reason for low power factor is supply system is due to installation of____________?
Correct answer: A. induction motors
- A. induction motors
- B. synchronous motors
- C. single phase motors
- D. d.c. motors
Explanation
Induction motors draw magnetising current and therefore consume substantial reactive power, causing a lagging power factor in supply systems. Synchronous motors can instead improve power factor when overexcited.
