Trip circuit current display
Abstract:
Circuit breakers may perform a variety of operations, including isolating a faulty part of the power system that may result in a cascading outage. However, circuit breaker operations may cause wear and tear of the tripping assembly components, which eventually cause the circuit breaker to wear out. Additionally, long periods of non-operations may cause the mechanical parts inside a circuit breaker to move sluggishly or, in some instances, fail to move at all. In an embodiment, a system includes a circuit breaker that trips to control power flow and an intelligent electronic device (IED) including an electronic display. The IED receives measurement data associated with a trip event for the circuit breaker, generates a current profile based on the measurement data, and presents the current profile via the electronic display.
