  • Panel discussion: The pros and cons of using SF6 gas in

    The use of solid dielectric for busbar systems, instead of SF 6, has the advantage that it enables the SF 6-based units to require no gas handling onsite during installation, commissioning and operation of the GIS equipment. Another advantage with the use of other alternatives is less impact on the environment and on the material used for the electrical insulation.

  • Gas Insulated or Air Insulated Switchgear

    The direct contribution of SF6 to greenhouse gas emissions is relatively low and I tend to think the advantages of a reliable electrical system outweigh these negatives. Lower system loses and less materials required during manufacture reduce the life cycle carbon emissions, potentially offsetting the negative effects of SF6.

  • Why SF6 or Sulfur Hexafluoride gas is better for arc

    SF6 is used in GIS – gas insulated system at pressures from 400 to 600 kPa absolute. Wide range of pressure The pressure is chosen so that the SF6 will not condense into a liquid at the lowest temperatures the equipment experiences. SF6 has two to three times the insulating ability of air at the same pressure.

    With this, the demand for SF 6 has grown, as it is the gas mostly used in switchgear. After all it’s largely safe to handle and allows for space-saving switchgear-designs. But more and more often, SF 6 is no longer the gas of choice. For a simple reason: if the gas escapes, it contributes to climate change.

    Cost savings resulting from greater efficiency. These are associated either with carrying out the mission (i.e., labor savings from automating or improving a workflow) or improvements in the mission itself. Better decision making. This typically has to do with making better decisions about location. Common examples include real estate site selection, route/corridor selection, zoning, planning, conservation, natural resource extraction, etc. Improved communication. GIS-based maps and visualizations greatly assist in understanding situations and story telling. They are a new language that improves communication between different teams, departments, disciplines, professional fields, organizations, and the public. Better geographic information recordkeeping. Many organizations have a primary responsibility of maintaining authoritative records about the status and change of geography (geographic accounting).
