Measuring Dew Point and Moisture in insulating gas 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
