The environmental impact of Sulphur Hexafluoride (SF6) means that its use in the electricity distribution industry is becoming increasingly regulated and restricted. Given that one tonne of SF6 is the equivalent of 23,500 tonnes of carbon, it is important that alternatives are investigated.
The projects objectives are as follows;

Production of a desktop study which details switchgear manufacturers progress into investigating compressed dry air as an alternative to SF6 for 33kV products.
Detail an implementation plan required to transition compressed dry air 33kV switchgear into business as usual.
