Undeniably, there have been a large number of developments in the high voltage field over the intervening years, but no such reference work has since been produced. There have been a number of key advances in materials. Polymeric insulators are still under major trials for transmission voltages but have become widely used in overhead lines at distribution levels. Cable insulation has moved from paper systems to various polymer-based materials. SF6 has taken over as an efficient and reliable insulation medium in high-voltage switchgear, and gas-insulated substations are now frequently the preferred option for new substations especially in urban areas. All of these changes have not been direct substitutions; they have each required a reconsideration of equipment configuration, and new installation and operational techniques.


ZnO surge arresters are also widely used worldwide. Their excellent over voltage protection characteristics have allowed design of modern compact systems to become more reliably achievable. The propagation of lightning and fault currents through earthing arrangements can now be modelled and predicted in much more reliable fashion. Much of this improvement in understanding has come from better use of

numerical methods such as boundary elements, finite element modelling and others,which has in turn put pressure on the experimental derivation of key material and system properties. The understanding of basic physical processes has also developed. The nature of breakdown in air and in other materials is now better characterized than it was twenty years ago.
Improvements have been made in instrumentation and experimental techniques. Who would have predicted thirty years ago, for instance, that it would now be possible to measure the distribution of space charge in solid insulation? So, the case seemed compelling for a new book reviewing, once again, the advances that have been made in high voltage engineering.

This project has had some sense of urgency because of the demographic trends in the research field. The age profile of researchers and experts in the field is disturbingly skewed, a number of experts having retired in the past few years or being about to retire. In many of the key areas of research and development, there is no obvious succession of expertise and a lack of any ongoing group within which the accumulated knowledge might be stored, protected and further developed. It was important then to encapsulate the accumulated wisdom and experience resident in these experts.
It is hoped, therefore, that this work on the one hand meets a need to update the advances that have undoubtedly been made in high voltage engineering during the past twenty years and, on the other hand, captures succinctly an accumulated knowledge which might otherwise be rather difficult to unearth through individual papers dispersed through the literature
