Switching reactors can impose a severe duty on the connected system, switching device, and shunt reactor. Due to the relatively small inductive current, the interrupting device attempts to clear at a forced current zero causing current chopping. If the interrupter’s contacts have not separated enough to sustain the system voltage, a re-ignition of the arc will occur. These high magnitude and high frequency re-ignitions can shorten the life of the reactor and the switching device. The Southern States’ RLSwitcher®, with its’ patented interrupter design, minimizes the probability and magnitude of these harmful re-ignitions.
