Abstract
A power system (8) comprising an electrical generator (12) connected to a transmission/distribution system (15) via a circuit breaker (14). The circuit breaker (14) further comprises a shorting element (20) and an impedance (22) in parallel thereto. The impedance (22) is closed immediately prior to closure of the shorting element (20), thereby inserting the impedance (22) into the circuit to reduce the switching transients caused by an out-of-phase condition between the current generated by the electrical generator (12) and the current carried by the transmission/distribution system (15).
