On-Site SF Gas Analysis - MBW Calibration AG

MBW Report - SF 6 Gas Analysis www.mbw.ch How wet is my SF 6? Arguably the presence of humidity within SF 6 is the most significant contribution to poor SF 6 quality and therefore equipment reliability. Without the presence of water vapor the threat of corrosion, arcing and decomposition would not be so significant.Get price

sf 6 Gas Measurement Theory - MBW Calibration AG

Measurement of Water Vapor in Sulphur Hexafluoride, SF 6. Authors: Bob Hardy, RH Systems, Albuquerque, NM, USA Daniel Mutter, MBW Calibration, Wettingen, Switzerland. Sulphur hexafluoride, SF 6, is a non-toxic, inert, insulating and cooling gas of high dielectric strength and thermal stability. Due to its high dielectric strength, it is particularly suited for application in high power circuit breakers as well as in high-voltage cables, transformers, and switchgears.Get price

Plasma etching of Si and SiO2 in Sulfr hexafluoride–O2 mixtures: Journal of

Jun 04, 1998 · The products of reaction and etch rates of Si and SiO 2 in SF 6 ‐O 2 plasmas have been studied as a function of feed composition in an alumina tube reactor at 27 mHz, 45 W, and 1 Torr. There is a broad chemical analogy with CF 4 ‐0 2 plasmas. As in CF 4 ‐0 2 mixtures, the rate of Si etching and 703.7‐nm emission from electronically excited F atoms each exhibit distinct maxima as a function of feed gas composition; these data support a model in which fluorine atoms, the etchingGet price

Sulfur hexafluoride - Wikipedia

Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air. It is generally transported as a liquefied compressed gas. The concentration of SF 6 in Earthtroposphere reached 10 parts per trillion in year 2019, rising at 0.35 ppt/year. The increase over the prior 40 years was driven in large part by the expanding electric power sector, including fugiGet price
