  • SF6 Gas Detection For HV GIS Switchgear - Crowcon

    9 mins readSep 30, 2020SF6 gas has virtually replaced oil and air as the dielectric insulator in medium (MV) and high (HV) circuit breakers, switchgear, gas-insulated substations and electrical equipment. Despite SF6 being an inert gas during normal use, when electrical discharges occur through the operation of high voltage equipment insulated with SF6, highly toxic by-products are produced that pose a serious
