Abstract: A hybrid surge protector architecture is configured to accommodate a plurality of replaceable L-shaped communication signal surge protection modules and a multi receptacle AC voltage terminal strip in the same housing architecture. The modules may be configured to provide surge protection for different types of communications signal lines. The hybrid surge protector has a housing structure which contains a floor, a vertical wall and convex cover. A first portion of the wall has an opening in which an AC voltage terminal strip is installed. A second portion of the wall has an aperture for a plurality of communication signal surge protection circuit modules. Hot and neutral leads of the terminal strip are coupled to input ports of the AC voltage surge protection circuit. A reference ground conductor for the terminal strip and the AC voltage surge protection circuit is mounted along the housing floor adjacent to the terminal strip.

Abstract: A method for detecting lightning as an electrical atmospheric disturbance and for providing an indication of the geographic position of that disturbance includes the stationing of at least three receivers at known geographic locations in spaced relationship to each other. Signals are encoded at each of the receivers representative of the time of arrival of an electrical indication of an emission from the lightning strike, in relation to a common timing source. All of the encoded signals are transmitted to a central facility and thereafter processed for deriving the position of the lightning strike irrespective of whether the position of the lightning occurred within or outside the perimeter bounded by the three receivers. The system is synchronized with the U.S. Coast Guard LORAN navigation network, and includes various features which permit a more accurate analysis of lightning position.

Abstract: A lightning ground stroke location system employs a time-of-arrival discrimination scheme which uses, as its time synchronization base, the U.S. Coast Guard LORAN-C navigation network. The system comprises a plurality (at least three and preferably four) of geographically separated lightning stroke monitoring stations. Each station contains a lightning stroke detector and a timing signal generator that is synchronized with the timing signal generator at each other respective detection location. The timing signal generation equipment at each receiver is comprised of a LORAN-C signalling responsive receiver which monitors the same encoded signal group emitted from a common LORAN-C reverence source. Each of the ground stroke detection stations is further connected via a respective communication link to a central processing facility.
