insulating gas Decomposition in Gas-Insulated Equipment - IEEE Journals

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