SF6 insulated leakage Draeger

Abstract. All sf 6-insulated equipment leaks to some degree.These losses of sf6 gas are usually low and usually less than 2% of the whole gas content of typical GIS. They occur slowly and almost undetected for many years, until a low gas pressure alarm sounds. Over the last fifteen years, manufacturers have continuously

  • SF6 Transmitter - draeger.com

    When insulating switchgear or transformers, sulfur hexafluoride (SF6) is used. Since it is technically almost impossible to hermetically seal these systems, emissions can escape into the environment. Gas detection systems from Dr ger make it possible to detect even the smallest leaks
