Shunt reactors are the most compact and cost efficient means of compensating capacitive generation in long transmission lines. They are placed permanently in service to stabilize power transmission, or switched in under light load conditions.

Neutral grounding reactors are designed to protect a system against phase-earth fault currents for a given fault time duration. Neutral-reactor grounding has a relatively low-impedance, somewhere between direct grounding an isolated neutral, limiting the failure current to a secure level without involving too high voltage on the healthy phases.

Prolec GE designs and manufactures both types of reactors to meet our customers’ needs.
