Ferranti effect can be compensated by using:
- Series capacitor
- Shunt capacitor
- Shunt reactors
- All of these
Correct answer: 3. Shunt reactors
Explanation: When medium or long electric power transmission lines are operated at no-load or light-load conditions, the receiving-end voltage becomes more than the sending-end voltage.
The phenomenon of rise in voltage at the receiving-end of a transmission line during no load or lightly load condition is called the Ferranti effect.
Ferranti effect is compensated by using shunt reactors that are provided to absorb a part of the charging current.
