Description
The unit has a special SF6 chamber that limits the transient recovery voltage (TRV) when the reactor is switched off. This reduces the probability of restrikes in the chamber after an inductive current is interrupted. The switch is installed in shunt reactor feeders at HV and EHV substations.
