The voltage drop, for constant voltage transmission is compensated by installing__________?
Correct answer: C. synchronous motors
- A. inductors
- B. capacitors
- C. synchronous motors
- D. all of above
- E. none of the above
Explanation
Voltage drop caused by reactive power can be reduced by an overexcited synchronous motor, which supplies leading reactive power and improves voltage regulation. Inductors absorb reactive power and generally increase the drop, so they are not suitable here.
