Abstract
A fault indicator for detecting the occurrence of a fault current in a monitored conductor and providing a contact closure and a light indication indicative thereof includes a rotatably mounted indicator flag. The flag is positioned in either a reset indicating or a fault indicating state by a four-pole magnetic pole piece, which is magnetized to an appropriate magnetic orientation by momentary application of a current to an actuator winding on the pole piece. A first magnetically actuated reed switch in an auxiliary magnetic circuit associated with a first pole of the magnetic pole piece and including the actuator winding and a first bias magnet closes upon occurrence of the fault current to connect an internal lithium battery to an LED visible from the exterior of the fault indicator housing. A
second magnetically actuated reed switch associated with a second pole of the magnetic pole piece and including the actuator winding and a second bias magnet closes upon occurrence of the fault current for external signaling or control purposes.
second magnetically actuated reed switch associated with a second pole of the magnetic pole piece and including the actuator winding and a second bias magnet closes upon occurrence of the fault current for external signaling or control purposes.
