Series capacitors are used to
- A. Improve line frequency and eliminate harmonics
- B. Compensate for line inductive reactance
- C. Neutralise line capacitive reactance
- D. None of the above
Answer: B. Compensate for line inductive reactance
Explanation: Series capacitors inserted directly in the line cancel part of the inductive reactance (Xnet = XL − Xc), reducing line impedance, enhancing power transfer capability, and improving voltage regulation.
