D. Shunt reactors
Answer: A. Shunt capacitors
Explanation:
Shunt capacitors:
- Whenever an inductive load is connected to the transmission line, power factor lags because of lagging load current.
- To compensate this, a shunt capacitor is connected which draws current leading the source voltage.
- The power factor can be improved.
- Shunt capacitors in an EHV line is used to improve fault level and voltage profile.
- This method is used to improve the power factor.
- Whenever an inductive load is connected to the transmission line, power factor lags because of lagging load current.
- To compensate, a shunt capacitor is connected which draws current leading the source voltage.
- The net result is an improvement in the power factor.
