RLSwitcher® Shunt Reactor Switch
Southern States recently shipped the first 550 kV RLSwitcher ®,
extending the existing family of definite purpose, shunt reactor
switches offered by Southern States.
Switching shunt reactors can impose a severe duty on the connected
system, the switching device, and the shunt reactor. The low
magnitude current the switching device is asked to clear, along with
the high magnitude and extremely fast transient recovery voltage
between the switchers contacts, establish an environment that can
lead to damaging reignitions. This has led to increased maintenance
requirements for the most commonly used switching devices as well
as shortened life for both the switching device and shunt reactor.
The Southern States’ RLSwitcher ®, with its patented interrupter design, deliberately
delays current interruption so that when current interruption does occur the likelihood of a
reignition is reduced and if they occur, are of a reduced magnitude. Additional benefits of the
Southern States RLSwitcher ® include:



Simplified, cost effective design that improves reliability
Reduced turn-to-turn stress on reactor windings
Reduced maintenance costs when compared to traditional electronically controlled
switching designs.
Southern States RLSwitcher ® shunt reactor switchers are available for voltages from 38
kV through 550 kV.
