  • A highly accurate algorithm for SF6 leakage detection

    To detect SF 6 leakage, the gas pressure is measured and compensated by gas temperature. Usually, the temperature of the container surface is measured instead of the actual gas temperature. However, the temperature of the container surface is affected by ohmic heating of the internal components and by ambient temperatureCited by: 1
