  • Fault indicator including a reed relay responsive to above normal current flow in a conductor
    Patent number: 4101826
    Abstract: A fault indicator includes a reed relay disposed for responding to a magnetic field surrounding a conductor particularly when conducting above-normal current. The relay triggers a latch which enables a counter and starts a pulse generator which, in turn, drives a flasher, and the pulses are counted for resetting the device by resetting the latch after a number of pulses have been counted. The reed relay is disposed in a position for adjustment of alignment and misalignment in relation to the conductor.
