Investigations on insulating gas-Free Gas Circuit Breaker Adopting CO2

Abstract. SF 6 gas has widely been used for high-voltage and large-capacity electric power equipment such as gas insulated switchgears (GIS) and gas circuit breakers (GCB) due to its excellent insulating and arc-quenching capability. Although SF 6 gas strongly contributes to achieve compactness and high reliability of the equipment, it has been recognized as one of the potent greenhouse gases and was designated to reduce the emissions at COP3 at Kyoto in 1997.
