  • Fault indicator tester with test bar and test chamber
    Patent number: 5680052
    Abstract: A testing apparatus for testing a sample fault indicator (11) of the type which has a current sensor (15), an automatic reset, an inrush restraint feature, and an indicator display (13) that are widely used by electric utilities for fault location of overhead and underground distribution power circuits. The first objective of the testing apparatus is to test the predetermined current threshold level of the sample fault indicator (11) which is specified by the producer. It provides for the simulation of a fault current condition by means of a pulse driver circuit (99). The output response of properly working fault indicator (11) under this test will cause the indicator display (13) to register a fault state. The second object provided by this apparatus is to test the automatic resetting of the sample fault indicator (11). It provides for simulating a reset signal (105) for a controlled duration of time.
