  • insulating gas Decomposition in Gas-Insulated Equipment - IEEE Journals

    Abstract: The increasing application of sf6 gas as an insulating gas has led to many studies on gaz sf6 decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, sf 6 decomposes to a wide variety of chemically active products which possess completely different properties from Sulfr hexafluoride.
