  • Byproducts of Sulfur Hexafluoride (SF6) Use in the

    SF 6 byproducts are difficult to detect chemically under normal working conditions. The presence of various SF 6 electrical discharge decomposition products and impurities (as well as the presence of SF 6 itself) makes measurement of the different byproducts problematic.

    SF6-filled joints detecting. Aug 23, 2011In thiscycle, the emissions are minimised, and used SF6 is recovered (at theend of the SF6-filled equipment lifecycle, for example) and either re-useddirectly or first purified and then re-used (SF6 re-use concept).2.5 The Voluntary Commitment on SF6 as an insulation and quenching gasIn the knowledge that SF6 has a very long lifetime in the

  • Ventilation Measurements Using Sulfur Hexafluoride (SF6

    Mar 20, 2019The primary reason is that it is easy to detect at low concentrations—even in the parts per billion (ppb) or parts per trillion (ppt) range and has very low toxicity. The best instrument to detect SF6 is an infrared spectrophotometer. Although the portable units are still a bit heavy, it allows direct reading measurements in real-time.

  • 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.
