What is a current limiting reactor?
Inrush current limiting reactors are designed to reduce the sudden high current surges that occur during capacitor switching in medium voltage power factor correction systems. These single-phase reactors regulate the current during switching and short-circuit conditions and protect system components, ensuring safe operation, extending the useful life of capacitors and switching equipment, and improving overall system stability.
