Shunt reactors. A shunt reactor is an absorber of reactive power and is the device most commonly used for reactive power compensation. 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.

The emf corresponding to the air-gap flux drives the stator current through the leakage reactance and conductor resistance of the stator coils. The voltage dropped across this winding impedance is small in relation to the air-gap voltage. Deducting this voltage drop from the air-gap voltage gives the terminal voltage of the loaded generator.

Shunt reactors contain the same components as power transformers, like windings, core, tank, bushings and insulating oil and are suitable for manufacturing in transformer factories. The main difference is the reactor core limbs, which have non-magnetic gaps inserted between packets of core steel. 3-phase reactors can also be made.
