Book Description
Drawn from the author's more than four decades of practical experience in the industry, The Vacuum Interrupter: Theory, Design, and Application first discusses the design and manufacture of the vacuum interrupter before delving into its general application. The book begins with a review of the vacuum breakdown process and what to consider when developing a design for a high-voltage application. It then discusses the vacuum arc and how its appearance changes as a function of current. This section concludes with an overview of existing contact materials, a summary of their advantages and disadvantages, an analysis of vacuum interrupter contact design, and considerations for the manufacture of vacuum interrupters. The next section on application describes the interruption process for low- and high-current vacuum arcs, examines the voltage escalation event that occurs if the contact gap is very small at the ac current zero, and explores the phenomenon of contact welding. It also studies the application of vacuum interrupters to switch load currents, circuit breakers, and reclosers. Owing to the increasing need for environmentally friendly interrupting systems, the development of vacuum interrupters will only intensify over time. With extensive references in each chapter for further exploration, this comprehensive guide provides essential, up-to-date knowledge to fully understand this vital technology.

Book Description
Title: The Vacuum Interrupter: Theory, Design, and ApplicationShelving guide: Electrical Engineering Dr. Paul Slade draws from his nearly six decades of active experience to develop this second edition of The Vacuum Interrupter: Theory, Design, and Application. This book begins by discussing the design requirements for high voltage vacuum interrupters and then the contact requirements to interrupt the vacuum arc. It then continues by describing the various applications in which the vacuum interrupter is generally utilized. Part 1 of this book begins with a detailed review of the vacuum breakdown process. It continues by covering the steps necessary for the design and the manufacture of a successful vacuum interrupter. The vacuum arc is then discussed, including how it is affected as a function of current. An overview of the development and use of practical contact materials, along with their advantages and disadvantages, follows. Contact designs that are introduced to control the high current vacuum arc are also analyzed. Part 2, on application, begins with a discussion of the arc interruption process for low current and high current vacuum arcs. It examines the voltage escalation phenomenon that can occur when interrupting inductive circuits. The occurrence of contact welding for closed contacts subjected to the passage of high currents, and for contacts when closing on high currents, is explored. The general requirements for the successful manufacture and testing of vacuum circuit breakers is then presented. The general application of vacuum interrupters to switch load currents, especially when applied to capacitor circuits, is also given. The interruption of high short circuit currents is presented along with the expected performance of the two major contact designs. Owing to the ever-increasing need for environmentally friendly circuit protection devices, the development and application of the vacuum interrupter will only increase in the future. At present the vacuum circuit breaker is the technology of choice for distribution circuits (5kV to 40.5kV). It is increasingly being applied to transmission circuits (72.5kV to 242kV). In the future, its application for protecting high voltage DC networks is assured. Audience This is a practical source book for engineers and scientists interested in studying the development and application of the vacuum interrupter Research scientists in industry and universities Graduate students beginning their study of vacuum interrupter phenomena Design engineers applying vacuum interrupters in vacuum switches, vacuum contactors, vacuum circuit breakers, and vacuum contactors It provides a unique and comprehensive review of all aspects of vacuum interrupter technology for those new to the subject and for those who wish to obtain a deeper understanding of its science and application Scientists and engineers, who are beginning their research into vacuum breakdown and aspects of the vacuum arc, will find the extensive bibliography and phenomenological descriptions to be a useful introduction

Book Description
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. Distributed by INSPEC. Annotation copyright by Book News, Inc., Portland, OR
Book Description
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.
