Current Limiting Reactors are connected in series with power system essentially to damp the short circuit fault current. During normal operation, continuous current flows through the reactor. Current limiting reactors are now widely used to control fault currents in both utility and industrial power systems.

Primary advantages of a current limiting reactor are:
- Reduction of electromechanical loading and thermal stress of transformers and switchgears.
- Stability improvement of primary bus voltage during a fault on feeder.
- Reduction of line-to-line fault current levels below line-to-ground faults or vice versa.
- Protection of distribution transformer and downstream power equipment and devices from the propagation of initial fast front voltage transients due to faults and circuits breaker operations.
- Increase in system reliability
