Abstract: A self-powered recloser includes a circuit breaker, an electrical actuator, an electrical generator, a capacitor, and a lever. When in an on state, the circuit breaker harvests power from a medium voltage line required to actuate its movable contact to interrupt current flow in the medium voltage line, and when in an off state, it does not harvest power from the medium voltage line. The electrical actuator is configured to transition the circuit breaker from the off state to the on state. The capacitor when charged is configured to provide the electrical actuator with the electrical power required to transition the circuit breaker from the off state to the on state. The lever is configured to be moved by an operative. Movement of the lever is configured to charge the capacitor via the electrical generator.

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.
