Shunt reactors

A shunt reactor is an absorber of reactive power, thus, increasing the energy efficiency of the system. It is the most compact device commonly used for reactive power compensation in long high-voltage transmission lines and in cable systems. The shunt reactor can be directly connected to the power line or to a tertiary winding of a three-winding transformer.

The shunt reactor could be permanently connected or switched via a circuit breaker. 

 

Hitachi Energy gapped core shunt reactor

Most oil-immersed shunt reactors manufactured by Hitachi Energy are based on the so-called gapped core concept. This technical concept is based on the core type technology that has been used within Hitachi Energy since the beginning of the 1970s.
