1. A self-powered recloser, comprising:
a circuit breaker;
an electrical actuator;
an electrical generator;
a capacitor;
a lever; and
control electronics;
wherein the circuit breaker when in an on state is configured to harvest power from a medium voltage line required to actuate its movable contact to interrupt current flow in the medium voltage line;
wherein the circuit breaker when in an off state is electrically isolated and configured not to harvest power from the medium voltage line required to actuate its movable contact to interrupt current flow in the medium voltage line;
wherein the electrical actuator is configured to transition the circuit breaker from the off state to the on state;
wherein 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;
wherein the lever is configured to be moved by an operative;
wherein movement of the lever is configured to charge the capacitor via the electrical generator;
wherein the control electronics are configured to control the electrical actuator to transition the circuit breaker from the off state to the on state; and
wherein the charged capacitor is configured to provide the control electronics with the required power to control the electrical actuator.
