This newly revised and updated reference presents sensible approaches to the design, selection, and usage of high-voltage circuit breakers-highlighting compliance issues concerning new and aging equipment to the evolving standards set forth by the American National Standards Institute and the International Electrotechnical Commission. This edition features the latest advances in mechanical and dielectric design and application from a simplified qualitative perspective. High Voltage Circuit Breakers: Design and Applications features new material on contact resistance, insulating film coatings, and fretting; temperature at the point of contact; short-time heating of copper; erosion and electromagnetic forces on contacts; closing speed and circuit breaker requirements; "weld" break and contact bounce; factors influencing dielectric strength; air, SF6, vacuum, and solid insulation; and dielectric loss and partial discharges, and includes updated chapters on capacitance switching; switching series and shunt reactors; temporary overvoltages; and the benefits of condition monitoring.

The electric power delivery system that carries electricity from large central generators to customers could be severely damaged by a small number of well-informed attackers. The system is inherently vulnerable because transmission lines may span hundreds of miles, and many key facilities are unguarded. This vulnerability is exacerbated by the fact that the power grid, most of which was originally designed to meet the needs of individual vertically integrated utilities, is being used to move power between regions to support the needs of competitive markets for power generation. Primarily because of ambiguities introduced as a result of recent restricting the of the industry and cost pressures from consumers and regulators, investment to strengthen and upgrade the grid has lagged, with the result that many parts of the bulk high-voltage system are heavily stressed. Electric systems are not designed to withstand or quickly recover from damage inflicted simultaneously on multiple components. Such an attack could be carried out by knowledgeable attackers with little risk of detection or interdiction. Further well-planned and coordinated attacks by terrorists could leave the electric power system in a large region of the country at least partially disabled for a very long time. Although there are many examples of terrorist and military attacks on power systems elsewhere in the world, at the time of this study international terrorists have shown limited interest in attacking the U.S. power grid. However, that should not be a basis for complacency. Because all parts of the economy, as well as human health and welfare, depend on electricity, the results could be devastating. Terrorism and the Electric Power Delivery System focuses on measures that could make the power delivery system less vulnerable to attacks, restore power faster after an attack, and make critical services less vulnerable while the delivery of conventional electric power has been disrupted.

Build fault-tolerant, robust, and distributed applications in Scala Key Features - Understand and use the concepts of reactive programming to build distributed systems running on multiple nodes. - Learn how reactive architecture reduces complexity throughout the development process. - Get to grips with functional reactive programming and Reactive Microservices. Book Description Reactive programming is a scalable, fast way to build applications, and one that helps us write code that is concise, clear, and readable. It can be used for many purposes such as GUIs, robotics, music, and others, and is central to many concurrent systems. This book will be your guide to getting started with Reactive programming in Scala. You will begin with the fundamental concepts of Reactive programming and gradually move on to working with asynchronous data streams. You will then start building an application using Akka Actors and extend it using the Play framework. You will also learn about reactive stream specifications, event sourcing techniques, and different methods to integrate Akka Streams into the Play Framework. This book will also take you one step forward by showing you the advantages of the Lagom framework while working with reactive microservices. You will also learn to scale applications using multi-node clusters and test, secure, and deploy your microservices to the cloud. By the end of the book, you will have gained the knowledge to build robust and distributed systems with Scala and Akka. What you will learn Understand the fundamental principles of Reactive and Functional programming Develop applications utilizing features of the Akka framework Explore techniques to integrate Scala, Akka, and Play together Learn about Reactive Streams with real-time use cases Develop Reactive Web Applications with Play, Scala, Akka, and Akka Streams Develop and deploy Reactive microservices using the Lagom framework and ConductR Who this book is for This book is for Scala developers who would like to build fault-tolerant, scalable distributed systems. No knowledge of Reactive programming is required.

Here-in one current, comprehensive source-is a wealth of both theoretical and practicalinformation on circuit interruption. Twenty-two authorities at the leading edge of researchand development provide a solid grasp of circuit breaker design and performance... and that's knowledge you can put to work immediately!arcuit Interruption surpasses other books in completeness and currency-includingcoverage of the sulfur hexafluoride puffer, the vacuum breaker, and the low-voltagemolded-case breakers, that are taking the place of many older types. In addition to thelatest theories and techniques, this major volume examines promising future trends.More than 400 clear illustrations help make the text easy to follow, and over 620 keyreferences point the way to the best places for continuing study.Today, the field of circuit interruption is so diverse that a thorough single source reallystands out. arcuit Interruption is that- source, the perfect reference for electrical, electronic,power, and design engineers; and researchers investigating circuit breaker design,interaction of breakers and power circuits, power transmission, power distribution,circuit interruption, electric contacts, and gaseous conduction. Moreover, this exceptionalbook serves as an excellent source for practicing power engineers as well as an invaluablesupplement to graduate-level engineering courses in circuit interruption, transmission,and distribution of power . . . and a supplement in professional seminars and society/association courses.
