HV switchgear - There is a green alternative

(Eaton Corporation, 2008) High voltage switchgear is one of the few applications where the use of SF6 gas is still permitted under greenhouse gas regulations. This is based on the premise there is no viable alternative. However, in the range1-52kV there is a perfectly viable option in the form of vacuum switchgear with solid dielectric insulation. Vacuum switchgear is similar in size and technically equivalent, if not superior, to sf6 switchgear. It is being used increasingly by utilities in Europe for medium voltage (1-52kV) applications.
