Objectives To fully realise the benefits that g3 can offer through an understanding of its practical application and implications in its use as an alternative to SF6 through demonstration in a working environment. If successful this work package will allow the use of g3 filled equipment to be employed on the SPT transmission system. The implications on the use of this innovative gas on the equipment itself will be understood and staff training requirements will be identified. The necessary tools and equipment for handling g3 will be developed.
Abstract SP Transmission Limited (SPT) have implemented a project to reinforce the 400kV and 275kV substations at Kilmarnock South to facilitate the planned amount of renewable generation capacity contracted to be connected to the transmission system in South West Scotland. A new 400kV double busbar GIS substation will be provided and built with a footprint designed to accommodate a total of 15 bays with an initial provision of 3 bays equipped with 400kV GIS switchgear. The employment of GIS offers benefits over AIS such as reduced space requirements (10% of AIS at 400kV) high reliability, improved safety, long service, reduced maintenance requirements, and low life cycle costs. The main disadvantage of GIS is the use of large quantities of SF6. SF6 is an excellent insulator, and is widely used in the electrical industry in high-voltage air or gas insulated switchgear, but it is a greenhouse gas with an extremely significant impact on global warming. It is one of the six gasses listed in the 1997 Kyoto Protocol designed to lower greenhouse gas emissions worldwide. As part of the RIIO T1 Business Plan, SPT aspires to identify measures to improve overall business carbon footprint where appropriate. SPT manage their SF6 inventory in accordance with industry good practice, but until recently, there was no alternative to SF6 that featured equivalent switching and voltage-withstand capabilities. A number of companies are looking to develop environmentally friendly SF6 alternatives. GE Grid Solutions are one company who is leading this field and can now offer a revolutionary SF6-free solution, g3 which has been jointly developed with 3MTM, a leader in environmentally sustainable solutions. g3 has 98% less impact on global warming than SF6. With performances comparable to SF6, it is a suitable technology for the development of today’s new generation of clean high- and high voltage equipment. GE Grid Solutions has been contracted to install the new 400kV GIS switchgear including a Gas Insulated Busbar (GIB) at Kilmarnock South and has confirmed that one 400kV (GIB) can be installed with g3 as part of an innovation pilot.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
