Abstract:

Surge arrestor assemblies for railroad and like circuits utilize a high surface area to cross-sectional area, broadband equal potential grounding plane which is in the form of a loop. Surges are electrically coupled to the broadband equipotential grounding plane through surge arrestors. The assembly ensures that each arrestor "see's" the same impedance so that the voltage seen at the equipment is controlled. The grounding member is supported in recesses in mounting blocks which maintain its planar condition, and which also facilitate the connections to ground, lines, arresters and equipment.
