Gaseous Dielectrics III is a collection of papers presented at the Third International Symposium on Gaseous Dielectrics, held in Knoxville, Tennessee on March 7-11, 1982. This book is divided into 12 chapters, and begins with the elastic scattering of electrons in gases, particularly the measurements of differential cross sections at low energies for electrons in electron-attaching gases. The next chapters deal with the basic mechanism of gaseous dielectrics, particularly the spark formation, corona attenuation and distortion, and examples of gaseous dielectric systems. These topics are followed by discussions on the practical problems of impulse breakdown, as well as the influence of gas pressure, gap distance, field distribution, and overvoltage on the formative time lag for approximately uniform field distribution. Other chapters examine the concept of surface flashover and the decomposition, aging, and bioenvironmental effects of gaseous dielectrics. The final chapters look into their analysis, gas-insulated equipment, and the properties of hexafluorosulfide. This book will prove useful to basic scientists, engineers, and users of gaseous dielectrics.

Gaseous Dielectrics II focuses on the discussion of the progress and issues related with gaseous dielectrics, their efficient use by the electric power industry, and how they affect the environment. This book features contributors who have pursued extensive research on gaseous dielectrics. The discussion starts with a presentation of the fundamental physics covering the subject. In this regard, numerical analyses are presented to show the nature of gaseous dielectrics. This book then proceeds by presenting the fundamental mechanisms involving corona discharge and breakdown in air as well as discharge processes in SF6. Supporting the discussion are numerical calculations that show how the processes progress. A discussion of “new gaseous dielectrics is also presented. In this consideration, the breakdown behavior of new gases and gas mixtures as well as their strength are elaborated. This topic is followed by the evaluation of the effect of surface defects on the breakdown of gases and gas mixtures. Another part of the book discusses the effects of conducting particles to gases and gas mixtures in gas-insulated systems. A discussion of the decomposition of gases and gas mixtures is presented, including high-voltage testing of gases and gas mixtures. The bioenvironmental effects of dielectric gases are also discussed. This selection is a valuable source of information for readers who are interested in studying the industrial utilization of gaseous dielectrics.

Gaseous Dielectrics V presents the proceedings of the Fifth International Symposium on Gaseous Dielectrics, held in Knoxville, Tennessee on May 3–7, 1987. This book discusses the effective coupling between basic and applied research and technology achieved in this area. Organized into 12 chapters, this book begins with an overview of the status of theoretical calculations of excitation and ionization coefficients for electrons. This text then provides an extensive investigation into different phases of discharge development in electronegative gases. Other chapters consider the use of sulfur hexafluoride as a dielectric medium in rail systems and gas circuit breakers. This book reviews as well the primary requirements for a successful gas analysis program, with emphasis on measurement and interpretation methods. The final chapter deals with the progress in dielectric quality assurance of gas insulated substations (GIS), which has resulted from improved scientific knowledge of significant phenomena. This book is a valuable resource for electrical and electronics engineers.

The Sixth International Symposium on Gaseous Dielectrics was held in Knoxville, Tennessee, U.S.A., on September 23-27, 1990. The symposium continued the trans disciplinary character and comprehensive approach of the preceding five symposia. Gaseous Dielectrics VI is a detailed record of the symposium proceedings. It covers recent advances and developments in a wide range of basic, applied and industrial areas of gaseous dielectrics. It is hoped that Gaseous Dielectrics VI will aid future research and development in and encourage wider industrial use of gaseous dielectrics. The Organizing Committee of the Sixth International Symposium on Gaseous Dielectrics consisted of L. G. Christophorou (U.S.A.), F. Y. Chu (Canada), A. H. Cookson (U.S.A.), D. L. Damsky (U.S.A.), O. Farish (U.K.), I. Gallimberti (Italy), A. Garscadden (U.S.A.), E. Marode (France), T. Nitta (Japan), W. Pfeiffer (Germany), I. Sauers (U.S.A.), R. J. Van Brunt (U.S.A.), and W. Zaengl (Switzerland). The local arrangements committee consisted of members of the Health and Safety Research Division and personnel of the Conference Office of the Oak Ridge National Laboratory, and staff of the University of Tennessee (UTK). The contributions of each member of these committees, the work of the Session Chairmen, the interest of the participants, and the advice of innumerable colleagues are gratefully acknowledged.

This book presents a comprehensive overview of research on environmentally friendly insulating gases, in response to the urgent calls for developing alternatives to SF6 due to the increasing awareness of the threat it poses as a greenhouse gas. It covers gas dielectrics, SF6 and its mixtures, and potential alternative gases, providing fundamental information on gas discharge and gas insulation and especially focusing on the development of new environmentally friendly insulating gases over the last decade. The book begins by describing the insulating and arcing characteristics of SF6, followed by an introduction to the gas dielectrics performance of SF6 gas mixtures with buffer gases. The latest findings on new environmentally friendly insulating gases are described in detail, and suggestions for practical application are also provided. Graduate students and teachers involved in high-voltage and insulation engineering can use the book as teaching material. Researchers working in plasma science, laser action and related applied physics fields can also benefit from the book’s analytical approach and detailed data; engineers from the fields of electric power operation systems and electrical manufacturing will find it a valuable reference work for solving practical problems.
