C. Shunt resistance at the receiving End
D. None of these
Answer:B. Shunt reactors at the receiving End
Explanation:
Shunt reactors
- A shunt reactor is an absorber of reactive power, thus increasing the energy efficiency of the system.
- Shunt reactor limits the overvoltage.
- Shunt reactor uses as reactive power absorber.
- it is used to compensate the undesirable voltage due to line capacitance (Ferranti effect).
- The sending end voltage is higher than the receiving end voltage. The shunt reactor reduces the voltage when the receiving end voltage is higher than the sending end voltage.
- Therefore, it increases the energy efficiency of the power system.
- It is the most compact device commonly used for reactive power compensation in long high-voltage transmission lines and in cable systems.
- They are very costlier than series reactors.
