  • gaz sf6 Leak Detection Application Note - Advanced Energy

    the pressure/density switches that are currently used to monitor the SF 6 gas compartment for safety consideration are lacking sensi-tivity for rapid leak detection. Direct detection is normally a preferred and more reliable method as it relies on measuring trace concentration for leaking gas in the ambient air. However, incumbent SF 6

    The lower dielectric performance of the g3 mixture, compared with Sulfr hexafluoride, is easily mitigated by a higher filling pressure, set at 7 bar (relative). This pressure level allows the GIS to operate with no heating at temperatures down to -25 °C. Temperature rise tests were performed on a fully equipped bay.
