SF6 is a colorless, odorless, tasteless, non-toxic gas (down to -20 degrees C) which has nearly ideal properties as an arc-quenching medium. Ryan and Jones (electrical engineering, Sunderland Polytechnic and U. of Liverpool) review the characteristics of SF6, discuss arc modelling methods, its use in switchgears, operation of circuit breakers; and reflect upon its impact on regulations, testing and instrumentation. History and synthesis are neglected. Annotation copyrighted by Book News, Inc., Portland, OR
Drawing from his 40 years of experience in the field, Greenwood (engineering, Rensselaer Polytechnic) describes the development of vacuum switchgear technology from its earliest origins to the most recent designs now offered by companies around the world. The volume begins with a foundation in the physics of the vacuum arc, in vacuum breakdown, and in the fundamentals of current interruption in vacuum. A chapter on applications spans all devices from contactors through switches and reclosers to power circuit breakers. Maintenance is also addressed. There are four chapters on different aspects of design and another on testing. The chapter on manufacturing concentrates on the interrupter as its manufacture is so entirely different from that required for oil and gas-blast circuit breakers. Thoroughly illustrated.

This book is an invaluable reference source dealing with the general principles of the switchgear function and discussing topics such as interuption techniques, fault level calculationsm switching transients and electrical insulation.
This book is intended to serve as a textbook for course 'switchgear and protection' for B. Tech/B.E.Degree students of Electrical Engineering. It will also serve as a text reference for the students of diploma in electrical engineering. The common topics included in the syllabi of almost all engineering institutions in India are covered in this book.
Plant engineers are responsible for a wide range of industrial activities, and may work in any industry. This means that breadth of knowledge required by such professionals is so wide that previous books addressing plant engineering have either been limited to only certain subjects or cursory in their treatment of topics. The Plant Engineering Handbook offers comprehensive coverage of an enormous range of subjects which are of vital interest to the plant engineer and anyone connected with industrial operations or maintenance.This handbook is packed with indispensable information, from defining just what a Plant Engineer actually does, through selection of a suitable site for a factory and provision of basic facilities (including boilers, electrical systems, water, HVAC systems, pumping systems and floors and finishes) to issues such as lubrication, corrosion, energy conservation, maintenance and materials handling as well as environmental considerations, insurance matters and financial concerns. One of the major features of this volume is its comprehensive treatment of the maintenance management function; in addition to chapters which outline the operation of the various plant equipment there is specialist advice on how to get the most out of that equipment and its operators. This will enable the reader to reap the rewards of more efficient operations, more effective employee contributions and in turn more profitable performance from the plant and the business to which it contributes.The Editor, Keith Mobley and the team of expert contributors, have practiced at the highest levels in leading corporations across the USA, Europe and the rest of the world. Produced in association with Plant Engineering magazine, this book will be a source of information for plant engineers in any industry worldwide.* A Flagship reference work for the Plant Engineering series* Provides comprehensive coverage on an enormous range of subjects vital to plant and industrial engineer* Includes an international perspective including dual units and regulations
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 UHV transmission has many advantages for new power networks due to its capacity, long distance potential, high efficiency, and low loss. Development of UHV transmission technology is led by infrastructure development and renewal, as well as smart grid developments, which can use UHV power networks as the transmission backbone for hydropower, coal, nuclear power and large renewable energy bases. Over the years, State Grid Corporation of China has developed a leading position in UHV core technology R&D, equipment development, plus construction experience, standards development and operational management. SGCC built the most advanced technology 'two AC and two DC' UHV projects with the highest voltage-class and largest transmission capacity in the world, with a cumulative power transmission of 10TWh. This book comprehensively summarizes the research achievement, theoretical innovation and engineering practice in UHV power grid construction in China since 2005. It covers the key technology and parameters used in the design of the UHV transmission network, shows readers the technical problems State Grid encountered during the construction, and the solution they come up with. It also introduces key technology like UHV series compensation, DC converter valve, and the systematic standards and norms. - Discusses technical characteristics and advantages of using of AC/DC transmission system - Includes applications and technical standards of UHV technologies - Provides insight and case studies into a technology area that is developing worldwide - Introduces the technical difficulties encountered in design and construction phase and provides solutions
