Abstract:
1. A faulted circuit indicator device for mounting on an overhead conductor cable for electrical power distribution systems to detect an abnormally high electric current therein, comprising: a housing formed of front and back walls, opposed side walls, and a closed bottom wall, all being integrally connected together so as to define an enclosure; current sensing circuitry disposed in said housing enclosure for detecting the presence of the abnormally high electric current in the overhead conductor cable; an indication unit being joined to the closed bottom wall of said housing and being responsive to said current sensing circuitry to produce a visual indication in the presence of the abnormal high electrical current; a clamping mechanism disposed above said housing for securely mounting the cable therein to detect the abnormally high electric current; said clamping mechanism being formed of a yoke and a pair of opposed pressure plates; and compression spring means for resiliently urging said pair of opposed pressure plates upwardly for automatically trapping the cable in a fixed central position between said yoke and said pair of opposed pressure plates.
