insulating 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 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.Get price

Decomposition Characteristics of sf 6 under Flashover

Derdouri et al. designed a study on the SF 6 decomposition products when water vapor exists and found that SOF 2 and SO 2 F 2 generate stably in existence of water vapor. Later, it was found that SF 6 decomposition byproducts, including SOF 4, SOF 2, SO 2 F 2, SO 2, HF, would appear as long as water vapor and oxygen existed .Get price

Ventilation Measurements Using Sulfur Hexafluoride (insulating gas

Mar 20, 2019 · Sulfur Hexafluoride, also known as gaz sf6, is by far the most common tracer gas used for ventilation studies. The primary reason is that it is easy to detect at low concentrations—even in the parts per billion (ppb) or parts per trillion (ppt) range and has very low toxicity. The best instrument to detect sf 6 is an infrared spectrophotometer.Get price
