sf6 gas Decomposition in Gas-Insulated Equipment - IEEE Journals

gaz sf6 Decomposition in Gas-Insulated Equipment Abstract: The increasing application of sf 6 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 Sulfr hexafluoride.Get price

Sulfr hexafluoride Monitoring System for GIS – GE Grid Solutions

SF 6 Monitoring System for GIS. With worldwide scrutiny on SF 6 gas usage, increased environmental reporting requirements and even possible penalties, precise early detection of small gas leaks in Gas Insulated Substations that use so much SF 6 is essential. The B Watch uses the latest generation of EMC resistant digital gas sensors to continuously measure gas pressure and temperatures in order to track changes in density and detect gas leaks down to 0.1% per year.Get price
