SF6 Breakers detection systems for Ultra High Voltage

SF6 Breakers detection systems for Ultra High Voltage

This paper develops a new detection system, for the first time, to detect the gas concentrations of the SF6/N2 mixture in extra/ultra-high voltage power transmission systems. The concentrations of SF6 and N2 are calculated from the thermal conductivity function of the mixture gas.
