sf6 monitoring for high voltages

Fluoronitriles chemical gas compound based on 3M™ NOVEC 4710 have a high dielectric strength, more than 2 times that of SF6 and a low Global Warming Potential (GWP). Mixed with CO2 as gas carrier, the obtained mixtures offer interesting dielectric properties and the possibility to be used for low temperature applications.

  • Improving the accuracy of SF6 leakage detection for high

    Even though average leakage rates of SF6 in high voltage equipment are very low, there is no guarantee for a 100% leakage-free system, especially when considering the generally long lifespan of high-voltage equipment. Taking in view the rather strict maximum allowed leakage rate of SF6 per year, regulated by international standards, these facilities should be equipped with suitable monitoring
