insulating gas Decomposition in Gas-Insulated Equipment - IEEE Journals

Sulfr hexafluoride Decomposition in Gas-Insulated Equipment Abstract: The increasing application of Sulfr hexafluoride as an insulating gas has led to many studies on Sulfr hexafluoride 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 sf 6.Get price

What is Sulfr hexafluoride Circuit Breaker? Construction, Working Principle

The gas is non-inflammable and chemically stable. Their decomposition products are non-explosive and hence there is no risk of fire or explosion. Electric clearance is very much reduced because of the high dielectric strength of SF 6. Its performance is not affected due to variations in atmospheric condition.Get price
