Sulphur hexafluoride gas decomposition products of fixed

Abstract: A reliable diagnostic technique of Gas insulated switchgear condition monitoring is used in this research for the detection of Sulphur hexafluoride gas (sf6 gas) decomposition products due to its high sensitivity and anti-electromagnetic interference; it is known as decomposition by-product method. A simulated coaxial decomposition chamber was designed and used to simulate the decomposition of sf6 gas under the effect of fixed metallic artificial defect on the surface of the spacer at theGet price

insulating gas Decomposition in Gas-Insulated Equipment - IEEE Journals

Abstract: The increasing application of Sulfr hexafluoride as an insulating gas has led to many studies on sf6 gas 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 Sulfr hexafluoride.Get price

SILICON OXIDE DECOMPOSITION AND DESORPTION DURING THE THERMAL

The thermal oxidation of silicon is normally considered to occur via two different routes. At higher O 2 pressures and lower temperature SiO 2 (s) film growth occurs ("passive" oxidation), while at lower O 2 pressures and higher temperature SiO(g) is desorbed in an etching process ("active" oxidation).Get price
