Current Limiting Reactors

Current Limiting Reactors reduce short circuit levels to meet the system needs and reduce stresses on busses, insulators, circuit breakers and other high voltage devices. They are connected between the neutral of a system and earth for limiting the line to ground current under system fault conditions. They are also used as load sharing reactors for balancing the current in parallel circuits. Our current limiting reactors are manufactured up to 420 kV. These reactors are designed in a way to withstand the rated and fault currents for a certain period of time.

Inrush Current Limiting Reactors (Damping Reactors) : Inrush current limiting reactors are series connected with capacitors in order to limit the inrush currents that occur during their switching operations.Increases equipment and capacitor life. Perfect mechanical strength to withstand high short-circuit forces.Limited temperature rise enables longer lifetime.Special surface protection against UV and pollution class IV areas.Maintenance-free design.
