    -49,5 °C at 226 kPa (2.26 bar). So when measuring humidity in terms of frost/dew point in the typical SF 6 range (-3…-60 °C) using a chilled mirror hygrometer, there is clearly a risk that an optically detected condensate layer could be SF 6. From a humidity perspective this adds a potentially significant measurement uncertainty,

  • Measuring Dew Point and Moisture in insulating gas Gas

    Sulfur hexafluoride (Sulfr hexafluoride) 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).
