Electric power system circuit breaker trip diagnostic

摘要

Disclosed herein are various systems and methods for monitoring the health of a circuit breaker. In various embodiments, a system may receive a voltage measurement across a trip coil assembly associated with a circuit breaker. The system may further receive a current measurement through the trip coil assembly. A plurality of transition points may be identified based on at least one of the voltage measurement and the current measurement, the plurality of transition points corresponding to at least one of a mechanical characteristic and an electrical characteristic of the circuit breaker during a trip event. A predictive analysis may be performed based at least in part on the plurality of transition points. An indication of the predictive health may be displayed.

1. A system for monitoring the health of a circuit breaker, comprising:
a first input configured to receive a voltage measurement across a trip coil assembly associated with a circuit breaker; a second input configured to receive a current measurement through the trip coil assembly; a processor in communication with the first input and the second input; and a non-transitory computer-readable storage medium in communication with the processor, comprising instructions configured to cause the processor to:
identify a plurality of transition points based on at least one of the voltage measurement and the current measurement, the plurality of transition points corresponding to at least one of a mechanical characteristic and an electrical characteristic of the circuit breaker during a trip event;perform a predictive analysis based at least in part on the plurality of transition points; anddisplay an indication of a predictive health of the circuit breaker based on the predictive analysis.
