Objectives Desktop study to undertake background research to establish if dry compressed air is a suitable alternative to SF6. The scope of this project is to undertake a desktop study which will include as a minimum; Literature review on compressed dry air as an alternative to SF6, identifying any associated risks and unforeseen challenges; Contact with supply chain to ascertain their progress in developing compressed dry air as an insulation medium; Identification of the likely parameters of the compressed dry air switchgear, associated operating functionality/performance, operational and maintenance requirement and risk assessments;Cost Benefit Analysis for potential field trials;Understand the parameters where compressed dry air can be utilised; Produce an implementation plan detailing the requirements if we were to transition compressed dry air 33kV switchgear into business as usual; Recommend potential for further work if initial timings are positive. 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.
Abstract The environmental impact of Sulphur Hexafluoride (SF6) means that its use in the ED 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.
