Abstract SF6 gas is widely used in power equipment such as gas insulated switchgear or gas circuit breaker. However, its global warming potential is 23,500 times higher than that of CO 2. In consideration of environmental protection, detection of SF6 gas leakage with high sensitivity is necessary.Author: Masaru Tatemi, Hisao Inami, Toshiaki Rokunohe, Makoto Hirose

Then a separate hose is used for re-filling of SF6 gas. The built-in SF6 gas regulator is used to fill the object with SF6 gas to desired filling pressure. FV0016 for gas filling of SF6 and evacuation of air is easy to move around and the risk of emission of SF6 is minimized thanks to different hoses for air and SF6 gas respectively.
