Advances in High Voltage Insulation and Arc Interruption in SF6 and Vacuum deals with high voltage breakdown and arc extinction in sulfur hexafluoride (SF6) and high vacuum, with special emphasis on the application of these insulating media in high voltage power apparatus and devices. The design and developmental aspects of various high voltage power apparatus using SF6 and high vacuum are highlighted. This book is comprised of eight chapters and opens with a discussion on electrical discharges in SF6 and high vacuum, along with the properties and handling of SF6 gas. The following chapters focus on high voltage breakdown and arc interruption in SF6 and in vacuum; various types of SF6 gas insulated circuit breakers and metal enclosed switchgear, together with their design considerations; and application of SF6 gas in some insulated equipments. The final chapter addresses the various problems relating to the development of vacuum switchgear and considers some solutions that led to the successful development of vacuum interrupters of acceptable quality. This monograph will be of direct use to engineers in industry and those with electricity supply and utility establishments, as well as graduate students and research workers who want to familiarize themselves with the investigations and the results on the various phenomena relating to SF6 and high vacuum and their practical applications.

The increase in demand for electricity and the growing energy density in metropolitan cities have made it necessary to extend the existing high voltage network right up to the consumer. Stepping down the voltage from transmission to the distribution level at the substations located near the actual consumers not only yields economic advantages, but also ensures reliable power supply. Such substations are required to meet a number of severe requirements, including small installation size, effective protection against atmospheric pollution and moisture, noiseless operation, nonexplosive and flame resistant, reduced maintenance, minimal radio interference while providing excellent electric characteristics. Conventional substations using atmospheric air as the main dielectric cannot satisfy these requirements, but totally enclosed substations using sulphur hexafluoride (SF6) gas insulation that are also known as Gas Insulated Substations (GIS). GIS is now in widespread use in the electrical power industry, especially in metropolitan areas. This book will serve as a valuable reference for the novice as well as the expert who needs a wider and detailed scope of coverage within the area of GIS. Gas Insulated Substations provides a comprehensive coverage of a wide range of topics which include: * Introduction to GIS & Properties of SF6 * Layout, Design, Construction, Testing & Maintenance of GIS * Special Problems and Diagnostic Techniques * VFTO Phenomena and its Effects in GIS * Service Experience * Standards Specifications * Future Trends * Extensive References Gas Insulated Substations (GIS) is the first single source for authoritative information on the state of the art in GIS.

Switching in Electrical Transmission and Distribution Systems presents the issues and technological solutions associated with switching in power systems, from medium to ultra-high voltage. The book systematically discusses the electrical aspects of switching, details the way load and fault currents are interrupted, the impact of fault currents, and compares switching equipment in particular circuit-breakers. The authors also explain all examples of practical switching phenomena by examining real measurements from switching tests. Other highlights include: up to date commentary on new developments in transmission and distribution technology such as ultra-high voltage systems, vacuum switchgear for high-voltage, generator circuit-breakers, distributed generation, DC-interruption, aspects of cable systems, disconnector switching, very fast transients, and circuit-breaker reliability studies. Key features: Summarises the issues and technological solutions associated with the switching of currents in transmission and distribution systems. Introduces and explains recent developments such as vacuum switchgear for transmission systems, SF6 environmental consequences and alternatives, and circuit-breaker testing. Provides practical guidance on how to deal with unacceptable switching transients. Details the worldwide IEC (International Electrotechnical Commission) standards on switching equipment, illustrating current circuit-breaker applications. Features many figures and tables originating from full-power tests and established training courses, or from measurements in real networks. Focuses on practical and application issues relevant to practicing engineers. Essential reading for electrical engineers, utility engineers, power system application engineers, consultants and power systems asset managers, postgraduates and final year power system undergraduates.

The book is written for students as well as for teachers and researchers in the field of High Voltage and Insulation Engineering. It is based on the advance level courses conducted at TU Dresden, Germany and Indian Institute of Technology Kanpur, India. The book has a novel approach describing the fundamental concept of field dependent behavior of dielectrics subjected to high voltage. There is no other book in the field of high voltage engineering following this new approach in describing the behavior of dielectrics. The contents begin with the description of fundamental terminology in the subject of high voltage engineering. It is followed by the classification of electric fields and the techniques of field estimation. Performance of gaseous, liquid and solid dielectrics under different field conditions is described in the subsequent chapters. Separate chapters on vacuum as insulation and the lightning phenomenon are included.

Vacuum switches now dominate the medium-voltage sector (below 30 kV) for all power switching functions. Allan Greenwood is a world authority in this field; in this book he shows how vacuum arcs and current interruption in vacuum are different from gaseous arcs and interruption in gas circuit breakers, and leads the reader to understand these differences - thereby enabling successful design, construction and use of vacuum switchgear. This comprehensive treatment (including an introductory historical perspective) makes the book useful for users and manufacturers as well as designers.
