15 kV Lightning Arrestor Standalone Assembly

The 15kV Lightning Arrestor Standalone Assembly guards against the very high potential difference that may develop between a Central Office incoming cable sheath and substation ground due to a lightning strike or Ground Potential Rise. In the event of an over-voltage caused by a lightning strike inside the Zone of Influence of a power substation, the 15kV lightning arrestor will begin to conduct and drain the lightning surge to the substation ground grid. The Model #751126/1 15kV Lightning Arrestor Assembly clamps the electrical potential induced by a lightning strike to 15kV until the surge decays. Once the voltage surge decays below the firing point of the lightning arrestor, the lightning arrestor ceases to conduct.
