Based on a successful IEE International Vacation School series, this book aims to give an appreciation of present day high voltage transmission and distribution systems. All the key components of HV power systems are covered from insulation systems, overhead lines, cables and bushings to switchgear and transformers. Electric power and HV transmission and distribution systems including HVDC and power electronic systems are also considered. The book gives details of design and testing techniques and of testing and measuring equipment. It provides an overview of transmission and distribution systems, technical, commercial and environmental considerations. Recent developments in testing and measuring technology are reviewed and the uses of fibrebased condition-monitoring strategies and life-management of electrical equipment are described. The book looks at HV equipment and installation both from the point of view of the provider and the user, covering everything from specification and testing to overall system co-ordination. Dynamic changes which have taken place during the past decade are also considered, such as the effects of privatisation and market influences in the UK and abroad. The book will be ideal for engineering students, lecturers, new graduates entering the high voltage field, practising engineers and anyone wishing to extend their knowledge in this area.
