Professor Dennis J Allan
BSc(Eng), FREng, CEng, FIEE, FIMechE, FIEEE


Professor Dennis Allan is an engineering consultant working in the area of electrical power systems technology, with particular interest in the design and application of plant for the transmission and distribution of electricity. At present he is working as a sub-consultant to PB Power on a number of overseas projects. In the recent past he has provided consultancy services to NGC, Midlands Electricity, East Midlands Electricity, Eastern Group and Yorkshire Group. His overseas clients include EPRI in the US, GE-Prolec in Mexico, CLP Power in Hong Kong and TransGrid in Australia.

Prior to 1997, after 47 years in the transformer industry with BTH, AEI and GEC he held the appointment of Director and Technical Manager for GEC ALSTOM T & D Transformers Ltd. at Stafford. Here, he was responsible for all technical activities in the Company. He has experience in the design, manufacture and testing of transformers up to 1000MVA rating and up to 800kV in voltage. His experience with the design of shunt and series reactors includes a 2000 MVAr series reactor at 400 kV and shunt reactors at 500 kV. He also has experience in the design, manufacture and testing of a phase shifting transformer at 400kV.

He is a Royal Academy of Engineering Visiting Professor in Principles of Engineering Design at UMIST, where he works with undergraduate and postgraduate students on MSc courses and PhD projects. He is, at present, External Examiner to the BEng and MEng courses at the University of Bath. He was elected to the Royal Academy of Engineering in 1993, where he has been active in the placement of young engineers on secondment to Japanese industrial companies.

He is Chairman of the Management Board of EAQA, the certification and accreditation body serving the power industry. He was chairman of the IEE Power Division in 1990 and served on the Council for two years. He was awarded the Institution Medal for outstanding achievement in Power Engineering in 1995. At present, he is a Senator on the Engineering Council representing registrants in College 'C'.

For eight years he was Chairman of CIGRE Study Committee 12 (Transformers) and Chairman of the British National Committee of CIGRE for six years. At present, he is Chairman of IEC TC 14 (Power transformers) and has been elected to serve for a second term.

He has specialist interests in high voltage engineering and testing, with particular emphasis on dielectric and insulation problems. He has also worked on the analysis of electromagnetic problems, interface problems of electrical plant, the design of low-loss equipment, diagnosis of faults and failure analysis, the application of condition monitoring to transformers and the development of effective design review procedures.

Professor Allan is responsible for the module on Power Transformers. He is also Chair of the Programme Management Committee.
