What is a  Shunt Reactor?

Shunt Reactor Definition

A shunt reactor is defined as an electrical device used in high voltage power systems to stabilize voltage during load changes.

Voltage Stabilization

It controls dynamic overvoltage and provides capacitive reactive power compensation in systems above 400kV.

Impedance Types

Shunt reactors come in gapped core or magnetically shielded air core types to maintain constant impedance and avoid harmonic currents.

Loss Measurement Methods

Losses are measured at lower voltages for high voltage reactors and scaled up; the bridge method is preferred due to the low power factor.

Operating Conditions

Must handle continuous voltage without overheating, ensuring it operates within safe temperature limits.
