The past decade has witnessed dramatic growth in the diversity and complexity of device applications where vacuum is required to support either high voltages or high electric fields. This is particularly true in thespace industry, specifically for the development of space-based pulse power systems. This book presents an overview of the technological advances that have occurred since the publication of the Editors earlier book High Voltage Vacuum Insulation: The Physical Basis. In this latest book, contributions from internationally recognized professionals and researchers in the field provide expanded treatment of the practical aspects of the subject. High Voltage Vacuum Insulation: Basic Concepts and Technological Practice provides a modern working manual for this specialized technology that is generic to a wide range of applications. The format makes the text suitable for use as a basis for special topic lecture courses at either the undergraduate or graduate level. Provides the fundamental physical concepts of the subject Focuses on practical applications Gives a historical survey of the field Includes a detailed account of system design criteria Reviews theoretical models developed to explain the pinhole phenomena Presents results of a series of experimental investigations on the subject

High-voltage electrophysical systems used for research in physics are becoming more and more common in engineering applications, as electrical insulation comprises one of the most important constituent components. This is the first monograph dealing comprehensively and on a scientific level with the insulation of such systems. In the first part of the book, the operating conditions and necessary requirements are analyzed, while the main insulation types are outlined. The second part describes the short- and long-term strengths of vacuums and gases, as well as liquid, solid, and hybrid dielectrics as functions of various influencing factors. The third and last part is devoted to the design of high-voltage insulation systems. The knowledge provided by this book will be useful to physicists designing experimental high-voltage devices as well as to electrical engineers in high-voltage technology, electrical insulation, and cable industries.

This book is based on the leading German reference book on high voltage engineering. It includes innovative insulation concepts, new physical knowledge and new insulating materials, emerging techniques for testing, measuring and diagnosis, as well as new fields of application, such as high voltage direct current (HVDC) transmission. It provides an excellent access to high voltage engineering – for engineers, experts and scientists, as well as for students. High voltage engineering is not only a key technology for a safe, economic and sustainable electricity supply, which has become one of the most important challenges for modern society. Furthermore, a broad spectrum of industrial applications of high voltage technologies is used in most of the innovative fields of engineering and science. The book comprehensively covers the contents ranging from electrical field stresses and dielectric strengths through dielectrics, materials and technologies to typical insulation systems for AC, DC and impulse stresses. Thereby, the book provides a unique and successful combination of scientific foundations, modern technologies and practical applications, and it is clearly illustrated by many figures, examples and exercises. Therefore, it is an essential tool both for teaching at universities and for the users of high voltage technologies.

This book covers major components of a high voltage system and the different insulating materials applied in equipment, identifying measurable materials suitable for condition assessment, and also analyses insulation fault scenarios that may occur in power equipment.

This study of insulating materials examines such topics as the manufacture of tempered glass, the glass-fibre core, the polymeric housing, the physics of pollution flashover and contamination, remedies for flashover and the testing of insulators.

This book addresses the very latest research and development issues in high voltage technology, specifically covering developments throughout the past decade. It is intended as a reference source for researchers and students in the field, but the unique blend of expert authors and comprehensive subject coverage means that this book is also ideally suited as a reference source for engineers and academics in the field for years to come.
