  • SF6 Decomposition in Gas-Insulated Equipment - IEEE Journals

    SF6 Decomposition in Gas-Insulated Equipment Abstract: The increasing application of SF6 as an insulating gas has led to many studies on SF6 decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, SF6 decomposes to a wide variety of chemically active products which possess completely different properties from SF6.

  • The decomposition products of sulfur hexafluoride (SF6

    Abstract. Sulfur hexafluoride (SF 6) is being widely used in a variety of industrial processes, commercial products and scientific fields due to its unique characteristics such as relatively low toxicity, extreme inertness and high dielectrics. However, the chemically stable gas is one of the most potent greenhouse gases (GHGs) that cause significantly global warming, and has been, thus, blanketed into the Kyoto Protocol.

    On the suspicion that SF 6 gas in a circuit breaker is contaminated or humid, we strongly recommend the use of drying and particle filters between switchgear and service cart. Moisture and both gaseous and dusty decomposition products as well as oil aerosols are adsorbed by special drying and particle filters during the recovery operation. Thus, service carts are protected effectively against contamination as most of the moisture and decomposition products are collected by the prefilter units.
