Abstract: Embodiments of the present disclosure provide a method for monitoring a circuit breaker, comprising the following steps: obtaining a characteristic force associated with an actuating mechanism of the circuit breaker over the time; and determining the time point when the closing and/or opening of the circuit breaker occurs by identifying a variation of the force. The step of determining further comprises determining the moment when a variation increase of the characteristic force occurs as the time point of the closing of the circuit breaker; and determining the moment when a variation decrease of the characteristic force occurs as the time point of the opening of the circuit breaker. The method can be used to accurately on-line monitor the closing and opening time point of the circuit breaker.
