Sulfr hexafluoride Decomposition in Gas-Insulated Equipment - IEEE Journals

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, gaz sf6 decomposes to a wide variety of chemically active products which possess completely different properties from gaz sf6. The accumulation of these decomposition products in the equipment has caused concerns regardingGet price
