This work has been successful in increasing the understanding of design challenges and finding possible solutions. Assessment of aged HV bushings ORE Catapult has carried out check testing and detailed failure analysis investigations of HV transformer bushings for a number of clients. The testing, analysis and strip-down activity uncovers the source of the degradation. This enables ORE Catapult to provide recommendations for improvements and modifications to the designs of the bushings and steps for the client to take to better monitor and assess degradation in-situ in the future. 2769 ORE Catapult National Renewable Energy Centre Offshore House, Albert Street, Blyth Northumberland NE24 1LZ T +44 (0)1670 359 555 F +44 (0)1670 359 666 [email protected] ore.catapult.org.uk
