In this paper, abnormal modes during operation are organized to evaluate the reliability of circuit breakers driven by linear motors. Next, an algorithm that automatically estimates the acceleration time from the load current of the linear motor and detects abnormalities in the circuit breaker from the acceleration time is examined. We report on the results of detecting abnormalities in mechanical components in an operation test of the circuit breaker with the proposed algorithm applied.
