Brochure SF6 decomposition Grid Solutions For determining the quality

From the environmental and health points of view, it is necessary to mitigate and control the emissions of the decomposition products from SF 6 destruction processes because most of them (e.g. S 2 F 10, SF 4 and HF) are highly reactive, corrosive and toxic, and few of them are also potent GHGs. This article aimed to introduce the fully fluorinated gas in industrial/commercial uses, and its toxic decomposition products in their environmental and health hazards, occupational exposure limits ...

  • SF6 DIAGNOSTICS AND SOLUTIONS — Powertech Labs

    Sep 01, 2016 · Sulphur hexafluoride (SF 6) is a non-toxic, odourless gas with unique electrical properties. For over 50 years, it has been used in high-voltage gas-insulated switchgear (GIS), where its excellent dielectric and arc-quenching properties make it an ideal insulating gas for medium- and high-voltage equipment. However, when the gas decomposes, it forms decomposition products that are toxic to maintenance personnel and harmful to equipment.
