  • Study on field demonstration of high‐sensitivity SF6

    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
