Damping Reactor for Capacitor Bank

The transient switching and inrush currents of a shunt capacitor bank can be limited by a damping reactor connected in series with the bank. Damping reactors are comparable to series reactors with low reactances. Their voltage strength requirements, however, are often higher than those of series reactors. Our damping reactors are used all over the world in various environmental conditions.

A complete selection of air core reactors is available for reactance applications,

Capacitor Switching Transient
Shunt Reactance
Neutral Current Limiting Reactance
Harmonic Filter
