Abstract

See full text

Control circuits for breaker control switches with a time-delay function and associated methods of making and using these devices to prevent an aurora event are disclosed. An exemplary control circuit may include a signaling device configured to provide a close signal for a circuit breaker to close; a timer configured to complete a countdown after the circuit breaker is opened; and a switch configured to close the circuit breaker after the countdown is complete and when the close signal is provided by the device. This may prevent engaging a piece of equipment with the power grid when the piece of equipment is out of phase or frequency with the power grid, which often leads to significant damage or destruction of the piece of equipment. Other embodiments are described.
