  • Measuring Dew Point and Moisture in SF6 Gas

    Sulfur hexafluoride (SF6) 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-gas 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 SulfurNews Tranformer Oil Support Hydraulic Oil About Us For Air

  • Online Dew Point Monitoring of SF6-Gas-Insulated Equipment

    Traditionally the dew point of SF6 has been measured by taking a gas sample from the tank, meaning that there has always been gas flow to account for during these measurements. Gas flow conceals the effect of very slow diffusion and vapor transients between gas and solid materials.

  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent man-made and naturally occuring greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom.
