  • SF6-alternative gases Leak Detection with return system

    Tracer gas leak testing is a simple and highly-efficient method of leak detection that provides high sensitivity, accuracy, and repeatability. A tracer gas leak test can be used to test parts with very low leak rates that are outside the range for conventional air-flow pressure decay and mass flow testing, or to replace bubble test methods.

  • Replacing SF6 with dry air reduces operational cost

    Mar 05, 2019SF6 equipment suppliers claim that their leakage is under the accepted 0,1% limit. The study done by PGE based on the data they have been collecting for 15 years shows that the real leakage rate is much higher. In fact, the average leakage in California totals around 2%, which is 20 times higher than the official data.

  • AirPlus TM - ABB

    dling and low leakage rates result in a small carbon footprint over the lifetime of the GIS. For this reason, SF 6 will remain the main insulation medium for GIS for years to come. However, an alternative such as AirPlus could further reduce the carbon footprint of the power grid.
