The Vacuum Interrupter Theory Design and Application

The Vacuum Interrupter Theory Design and Application

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 | The Vacuum Interrupter Theory Design and Application

Research Tracks in Urbanism: Dynamics Planning and Design in Contemporary Urban Territories

Research Tracks in Urbanism: Dynamics Planning and Design in Contemporary Urban Territories

Maybe the Global Village metaphor has never been more accurate than it is today where societies join forces in the fight against the COVID 19 pandemic in a global coordinated effort possibly never tested before in the known history of Humankind. Although we are sure that in the past some other shared demands have united the different peoples of the world this has never been so strongly necessary mainly in what the global scientific community is concerned. This is a fight for the survival of a society. However we should not lose sight of what we are fighting for. We fight together for people. Not just for the abstract value of Human life but for life in society as a whole including its moral and ethical aspects. The topics of this book are based on this claim on what makes it possible. We do not build our lives in a vacuum or in distant Invisible Cities but through a higher value which represents physical life in society: the City built by the discipline of Urbanism. This book is a spin-off of the International Research Seminar on Urbanism_SIIU2020. Inspired by the contents of twelve research seminars a group of researchers from the universities of Barcelona Lisbon and São Paulo discuss the contemporary agenda of research in Urbanism. Following the conference a selection of 35 original double-blind peer-reviewed research papers were brought together with different perspectives about such an agenda. | Research Tracks in Urbanism: Dynamics Planning and Design in Contemporary Urban Territories

Wrongful Convictions and Forensic Science Errors Case Studies and Root Causes

Wrongful Convictions and Forensic Science Errors Case Studies and Root Causes

Forensic Science Errors and Wrongful Convictions: Case Studies and Root Causes provides a rigorous and detailed examination of two key issues: the continuing problem of wrongful convictions and the role of forensic science in these miscarriages of justice. This comprehensive textbook covers the full breadth of the topic. It looks at each type of evidence historical factors system issues organizational factors and individual examiners. Forensic science errors may arise at any time from crime scene to courtroom. Probative evidence may be overlooked at the scene of a crime or the chain of custody may be compromised. Police investigators may misuse or ignore forensic evidence. A poorly-trained examiner may not apply the accepted standards of the discipline or may make unsound interpretations that exceed the limits of generally accepted scientific knowledge. In the courtroom the forensic scientist may testify outside the standards of the discipline or fail to present exculpatory results. Prosecutors may suppress or mischaracterize evidence and judges may admit testimony that does not conform to rules of evidence. All too often the accused will not be afforded an adequate defense—especially given the technical complexities of forensic evidence. These issues do not arise in a vacuum; they result from system issues that are discernable and can be ameliorated. Author John Morgan provides a thorough discussion of the policy practice and technical aspects of forensic science errors from a root-cause scientific analysis perspective. Readers will learn to analyze common issues across cases and jurisdictions perform basic root cause analysis and develop systemic reforms. The reader is encouraged to assess cases and issues without regard to preconceived views or prejudicial language. As such the book reinforces the need to obtain a clear understanding of errors to properly develop a set of effective scientific procedural and policy reforms to reduce wrongful convictions and improve forensic integrity and reliability. Written in a format and style accessible to a broad audience Forensic Science Errors and Wrongful Convictions presents a thorough analysis across all of these issues supported by detailed case studies and a clear understanding of the scientific basis of the forensic disciplines. | Wrongful Convictions and Forensic Science Errors Case Studies and Root Causes
