What I have learned about SF gas testing….in 2015…a Practical

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. Purity: <97% should be replaced, 97% and to 100% is good useable gas, 99.7 to 100% is new good gas. 3.Get price

Measuring Dew Point and Moisture in Sulfr hexafluoride Gas

Sulfur hexafluoride (sf6 gas) gas is an inert insulating gas of high dielectric strength and thermal stability, often used in the power sector for insulating high voltage lines, circuit breakers, transformers and other switchgear equipments. As sf6 is an inert gas, it can’t cause corrosion but in the presence of moisture it will cause formation of highly corrosive acidic by-products, such as Hydrogen Fluoride (HF) and Sulfur dioxide (SO2).Get price
