  • A 500-kV Circuit Breaker Using SF6 Gas - IEEE Journals

    Abstract: The first 500-kV 35 000-MVA breakers to go in service in the United States have been developed and subjected to extensive testing. They are built of modules which can be combined for voltages of 345 kV, 500 kV, and 700 kV. The interrupting medium is SF6 gas in a completely sealed 2-pressure system, operating at constant densities.
