Abstract: A monitoring system for a mechanically driven circuit breaker that includes fixed and moveable contacts, and a main actuator, wherein the moveable contact is selectively spaced from the fixed contact, and wherein the main actuator transitions the circuit breaker between states, the monitoring system comprising an actuation device; a sensor; and a processing unit. The actuation device applies a micro-motion to the actuator without the circuit breaker transitioning states; wherein the sensor acquires sensor data associated with the application of the micro-motion; wherein the sensor provides sensor data to the processing unit; and wherein the processing unit determines whether the circuit breaker has a fault using the sensor data.

Abstract: A vacuum circuit breaker comprises a vacuum breaker unit; and a drive unit. The drive unit includes an opening spring for biasing a movable contact of the vacuum breaker unit towards the open position; and a spring tension adjustment mechanism. The spring tension adjustment mechanism comprises an adjustment actuator; and a rigid coupling link connecting the adjustment actuator to the second end portion the opening spring. The adjustment actuator is arranged offset from an opening spring axis.
