insulating gas 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.Get price

2. Purity expressed in % of SF 6 in the gas sample tested 3. Decomposition products, usually measure by SO2 detection Typical values for above are: 1. Moisture: <50 ppmv for new gas, <150ppmv for gas in use in a breaker or GIS and 150ppmv is wet gas that needed drying or re-conditioning and 400ppmv is definitely dangerous to use. 2.Get price
