The Problem with Humidity in Sulfr hexafluoride Gas-Insulated Systems

Apr 17, 2018 · 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 insulating gas gas. To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS).Get price
