Development of an SF/sub 6/ high-voltage dc circuit breaker. Final report

Technical Report ·
OSTI ID:5508682

In a field trial on the West Coast high-voltage dc intertie, a circuit breaker designed much like an ac puffer breaker commutated currents of up to 1200 A. With minor modifications, devices based on this design should be able to handle 2200 A at 500 kV, thus increasing utility flexibility in operating dc systems.
