  • The Problem with Humidity in SF6 Gas-Insulated -

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

  • Gas density monitors - Product overview - WIKA

    Sulfur hexafluoride (SF6) is an extremely effective electrical insulator for medium- and high-voltage switchgear. For proper insulation, gas density must remain within certain levels. Furthermore, as SF6 is a potent greenhouse gas, it must not escape into the atmosphere.
