SF6 End-of-life DETERMINATION for HV MV

SF6 End-of-life DETERMINATION for HV MV

Within the electrical industry sf6 is used as an insulating medium for medium (MV) and high (HV) voltage electrical switchgear. A switchgear is the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate sections of electrical grids.
