摘要：

SF6 gas is widely used in electric power apparatus such as gas insulated switchgears (GIS) and gas circuit breakers (GCB) due to its excellent dielectric and arc-quenching performance. However, SF6 gas has recently been recognized as a greenhouse gas and it was decided to reduce its emissions at COP3 at Kyoto in 1997. Thus, surveys on the amount of emissions and efforts to reduce emissions have been continued all over the world. Simultaneously, studies on alternative gases to SF6 gas have increased[7-8]. In fact, studies on alternative gases, the purpose of which was to find a gas that had better performance than SF6 gas, had been carried out previously. However, the purpose of recent studies is to reduce environmental impact.
