Fault current diverter

摘要

A fault current diverter for use with high voltage electrical equipment is operative to divert fault current to ground by establishing a non-arcing low impedance current path to ground. The diverter includes a switching device having a moving contact which, in response to the triggering of a chemical propellant charge, is rapidly driven so as to pierce solid insulation and make contact with a high voltage conductor or terminal thereby to establish the non-arcing low impedance path.
