"Circuit Breaker With Overvoltage Protection"

Abstract: A circuit breaker (434) is provided for protecting dynamoelectric machinery. The circuit breaker includes a feeder input connection (527) connected to a feeder line (426). The feeder line is connected to a dynamoelectric machine. A substation connection (528) is connected to a substation bus (432). An interrupting breaker (530) is connected between the feeder input connection and the substation connection. A shorting switch (520) is connected to the feeder input connection, and an impedance device (510) is connected to the shorting switch and a ground or neutral (446). The impedance device, shorting switch and ground/neutral reduces excessive voltages on the feeder line when the feeder line is isolated from the substation by the circuit breaker, and the impedance device is selected to reduce a torque transient experienced by the dynamoelectric machine.
