Abstract:
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 includes a housing having an enclosure formed therein and current sensing circuitry for detecting the presence of the abnormally high electric current in the cable. An indication unit is responsive to the current sensing circuitry to produce a visual indication in the presence of the abnormally high electrical current. A clamping mechanism formed of a yoke and a pair of opposed pressure plates is disposed above the housing for securely mounting the cable therein to detect the abnormally high electric current. Compression springs are provided for resiliently urging the pair of opposed pressure plates upwardly for automatically trapping the cable in a fixed central position between the yoke and the pair of opposed pressure plates.
