  • The Problem with Humidity in sf6 gas Gas-Insulated - WIKA blog

    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).

    The self-healing property refers to that if the sf 6 is exposed to an arc, the gaz sf6 disassociates into various sulfur, fluorine, and sulfur-fluorine molecules. When the arc shuts down, the sulfur reacts with the fluorine, producing sf 6 again. The main thing is that the fluorine is not free to react with the circuit breaker parts.
