It is several years since any book has attempted to cover the range of issues in high voltage research and development. The area continues to be full of challenge and scope and this book focuses on developments in experimental methods, theory, modelling and HV technology through the past decade. The coverage includes advances in basic understanding and capability, for instance in earthing, numerical analysis, optical methods, the physics of air breakdown and partial discharge. It also addresses technological developments in key areas such as SF6 insulation systems, polymeric insulators and power cables, ZnO surge arrestors, and pulsed power. The unique blend of reputable contributors and comprehensive subject coverage makes this book an ideal reference source for engineers and researchers in the field for many years to come.
