  • 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 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).

  • Using Sulfur Hexafluoride as a Gaseous Tracer To Study

    that finally proved successful was to release the SF6 directly from a SF6 lecture bottle through a 0.006-inch hole in the lecture bottle cap (see fig. 3). The small hole resulted in a fine jet spray of the SF, that mixed well with the mine air. Mixing was further aided by moving the lecture bottle rapidly around the airway during release.
