The Problem with Humidity in sf6 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 SF 6 gas. To prevent operational and safety issues, it is important to measure and monitor humidity levels in gas-insulated switchgear (GIS).
