• Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride is inert in the troposphere and stratosphere and is extremely long-lived, with an estimated atmospheric lifetime of 800–3,200 years. [29] Measurements of SF 6 show that its global average mixing ratio has reached over 10 parts per trillion (ppt) as of April 2020, and is increasing by about 0.35 ppt (3.5 percent) per year.

    Sulfur hexafluoride is primarily of anthropogenic origin but also occurs naturally in minerals, rocks, and volcanic and igneous fluids. Concentrations of SF 6 in air have rapidly increased from a steady state value of about 0.02-0.05 to over 7 parts per trillion during the past 40 years, and are expected to continue increasing.

  • The Problem with Humidity in Sulfr hexafluoride Gas-Insulated Systems

    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 gaz sf6 gas. To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS).
