• Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent 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. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of

  • Water: The Most Powerful Impurity in Sulfr hexafluoride Gas - WIKA blog

    Sulfur hexafluoride is the gas most commonly used as insulator in power transmission and distribution switchgear. Water, however, can negatively affect the dielectric capabilities of sf6 gas gas. To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS).

    Sulfur and fluorine form a very useful chemical compound as sulfur hexafluoride (insulating gas). It is an excellent insulation gas, e.g. in medium and high-voltage switchgears of electricity grid operators. However, as sf 6 works in gas-insulated switchgears, it is highly susceptible to one natural enemy: moisture!

  • How Humidity Affects the Safety of sf6 gas-Insulated - WIKA blog

    When the humidity content of the gas reaches certain levels, the sulfur and fluoride begin to form highly toxic and corrosive products such as sulfur dioxide (SO 2), hydrofluoric acid (HF), and disulfur decafluoride (S 2 F 10). These compounds not only decrease the amount of dielectric insulator but also create an acidic environment that attacks and damages the internal surfaces of the gas tanks and can compromise safety.

  • Industrial gaz sf6 Gas Pressure and Measurement Products - WIKA USA

    Although sulfur hexafluoride is nontoxic and nonflammable, escaped gas in enclosed rooms displaces oxygen in the air and could lead to asphyxiation. SF 6 is also a potent greenhouse gas – 23,900 times more effective than carbon dioxide at trapping infrared radiation in the atmosphere. In addition, TD plant safety depends on the purity of SF 6 gas. Under normal conditions during an electrical discharge, the six fluorine atoms split from the sulfur atom to capture electrons; after quenching
