High Voltage and Power System Plant

HV research has been an integral part of the work of the EEPS group since the 1950s when the first laboratory was opened at the University. The National Grid High Voltage Research Centre is now home to the largest HV laboratory of any UK university and is capable of testing equipment designed for use on the 400kV power system.

Research work in the facility is split into a number of areas. Particular areas of competency include transformer insulation and monitoring, polymeric insulation and power system transients. We develop condition monitoring and lifetime assessment techniques for ageing power system plant infrastructure, study all the technical issues related to application of novel insulation materials in power system plant, and participate into technology innovation for aerospace applications.
