• The Problem with Humidity in insulating gas 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 Sulfr hexafluoride gas. To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS).
