FAULT INDICATOR AND MEANS FOR RESETTING THE SAME Abstract of the Disclosure A fault indicator for alternating current distribu- tion systems includes a pair of spaced pole pieces for receiv- ing therebetween at one end the conductor and at the other end a pivoted permanent magnet carrying a target that is biased to a fault indicating position by a stationary permanent magnet. The pole pieces are demagnetized on flow of fault current in the conductor. They are remagnetized by a winding which is energized by discharge of a capacitor that is charged through a rectifier from an oscillator circuit. The winding is carried by a receptacle into which the other ends of the pole pieces are inserted and a circuit is completed thereby to charge the capacitor. The receptacle is carried at one end of a tubular housing the other end of which has an eye to receive a claw of a live line tool for applying the fault indicator to and removing it from the conductor.
