wika sulphur hexafluoride leak check for gis

Sulfur hexafluoride (SF6) is an extremely effective electrical insulator for medium- and high-voltage switchgear. For proper insulation, gas density must remain within certain levels. Furthermore, as SF6 is a potent greenhouse gas, it must not escape into the atmosphere.

  • WIKA’s GPU-2000: Specifically Designed for Safe SF6 Handling

    Sulfur hexafluoride (SF 6) has excellent dielectric and heat transfer capabilities. That’s why it is the preferred insulator for power transmission and distribution (TD) switchgear. However, humidity in the gas can decrease its insulation strength and promote corrosion in the equipment, leading to serious health and environmental problems related to leaks. Therefore, one of the top priorities for TD engineers is to monitor the humidity level of gas-insulated switchgear (GIS). SF 6
