  • The Problem with Humidity in SF6 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).

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

    Sulfur hexafluoride, a highly effective insulator and arc quencher, is commonly found in the power transmission and distribution industry. But to protect equipment, personnel, and the environment, users must be aware of the common SF6 gas hazards and how to avoid them. Sulfur hexafluoride (SF 6), when sealed inside power transmission and distribution (TD) equipment, insulates switchgears, circuit breakers, and disconnectors by quenching dangerous arcs.

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

    Therefore, one of the top priorities for TD engineers is to monitor the humidity level of gas-insulated switchgear (GIS). SF 6 handling is crucial. As the humidity in SF 6 approaches the gas’s water saturation point, operators must make sure the wet gas is replaced with dry gas. Replacing Sulfur Hexafluoride. SF 6 handling can be tricky. The gas is nontoxic, but it easily displaces oxygen in enclosed areas, which can asphyxiate nearby personnel.

  • Switchgear - Wikipedia

    A switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.

  • Service - SF6 – FAQ - WIKA USA

    The quality of the SF 6 gas must be analysed, since it can lead to chemical reactions in the gas when used in gas-insulated switchgear, due to the high energy occurring there. An analysis of the SF 6 gas quality is always recommended and should be an integral part of the maintenance strategy, especially before any gas handling.
