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 medium voltage load break switch includes a main contact and a knife. The knife is rotatable about a pivot point to connect to and be in contact with the main contact and to rotate about the pivot point to disconnect from and be spaced from the main contact. The load break switch also comprises a vacuum interrupter that has a fixed contact and a moveable contact. A lever rotates about a rotation point and a shaft of the moveable contact is aligned along an axis of the vacuum interrupter, and the shaft of the moveable contact is linked to the lever.
