Design and delivery of Ireland’s largest transformer
Robert Le Roux
Sažetak
Due to constraints in the Irish transmission system, the Irish Transmission System Operator called for increased capacity in the network to cater for increased renewable generation by adding a 500 MVA, 400 kV transformer and a new 400 kV GIS substation on the Atlantic west coast. Due to the network configuration, the insulation level of Ireland’s 400 kV system is rated at 550 kV, resulting in more stringent requirements for design and testing to ensure insulation coordination. A detailed functional and technical specification was produced, which included stringent requirements for corrosion protection, over-fluxing, short circuit withstand, impedance envelope, conditional monitoring, testing and delivery. Delivery and installation of this large transformer to the remote location of the site, prone to heavy Atlantic swells and gale force winds, took place in winter, which increased the risk of moisture contamination of the oil and RIP-type bushings. Through careful planning and coordination, the entire operation worked out successfully.
