  • Study on field demonstration of high‐sensitivity SF6

    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

  • SF6 Circuit Breaker: What Are They? (Types and Operation

    Oct 23, 2020Due to its low gaseous viscosity, SF6 gas can efficiently transfer heat by convection. So due to high dielectric strength and high cooling effect, SF 6 gas is approximately 100 times more effective arc quenching media than air.. Due to these unique properties of this gas, SF6 circuit breaker is used in a complete range of medium voltage and high voltage electrical power system.
