Abstract
A lightning activated relay utilizes an electric or magnetic field responsive detector for determining the presence of atmospheric conditions potentially capable of producing lightning or for detecting the occurrence of lightning within a predetermined range. Switching circuitry responsive to the detector is provided for isolating electrical equipment from the electric power mains and isolating or grounding communications or other equipment susceptible to lightning damage when such conditions are detected or upon the occurrence of a temporary power interruption.
