insulating gas gas - WIKA South Africa

The plant safety of SF 6 gas-insulated switchgear is reduced significantly through low concentrations of decomposition products. These decomposition products arise during operation through arcing in moist or impure SF 6 gas. In order to detect even the smallest leakages or to warn ahead of gas emissions, we have a range of high-quality gas detectors and emission monitors.Get price

sf6 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 sf 6 decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, Sulfr hexafluoride decomposes to a wide variety of chemically active products which possess completely different properties from insulating gas.Get price
