sf6 insulated switchgear check for leaks Wika

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 (GIS).

  • SF6 Gas Hazards and How to Avoid Them - WIKA blog

    The best way to avoid SF 6 gas hazards is to continually monitor gas-insulated equipment for both quantity (to detect leaks) and quality (for current gas conditions). Then, when the gas has dropped below a certain level of purity, technicians can clean it. Here are just a few of WIKA USA’s innovative SF 6 gas solutions for greater safety and efficiency:
