  • Gas density monitors and gas density sensors for SF6 and

    Trafag gas monitoring devices measure the gas density directly, i.e. SF 6 Gas Density Monitors, with the unique gas density reference principle or the patented quartz tuning fork technology, i.e. SF 6 Gas Density Sensors, or by combining both principles, i.e.SF 6 Hybrid Gas Density Monitors. They thus offer the most reliable solution on the market by directly measuring theSF 6 gas density.

  • Gas-insulated substations are switching to g³, the SF₆

    It was just two years ago that GE announced a breakthrough in developing a substitute for SF 6 in gas-insulated equipment. Such a substitute had become necessary because SF 6, despite its undeniable qualities—its arc-quenching and dielectric capabilities—has a global warming potential (GWP) 23,500 times that of CO 2, with a lifetime in the atmosphere of over 3,000 years.
