SF6-alternatives Calibration for 132kv

SF6-alternatives Calibration for 132kv

SF6 and alternatives in electrical switchgear and related. Sulphur hexafluoride (SF6) has been used as an insulating and circuit breaking medium in switchgear for decades. With a global warming potential (GWP) of 22,8001, SF6 is the most potent greenhouse gas known and its use in switchgear can produce toxic by-products.
