Book excerpt: One of the most complex disciplines in electrical engineering is power system protection which requires not only the proper understanding of the different components of a power system and their behavior but also a good knowledge and analysis of the abnormal circumstances and failures that can occur in any element of a power system. Protective relaying is an integral part of any electrical power system. Relays are not required to operate during normal operation, but must immediately activate to handle intolerable system conditions. This immediate availability criterion is necessary to avoid serious outages and damages to parts of or the entire power network. The fundamental objective of system protection is to quickly isolate a problem so that the unaffected portions of a system can continue to function. Protective relays are the decision-making devices in the protection scheme. These relays underwent, through more than a century, important changes in their functionalities and technologies. In fact, the accuracy of relays depends not only on their hardware components but also on the manner of information processing to evolve the decision signal; this is what is called the data processing algorithm or the processing method. So, the research of the optimal method to obtain the most accurate decision in the fastest way is one major challenge in the numerical protective relay design. Power Supply Devices and Systems of Relay Protection provides a survey of protective relaying technology and its associated communications technology used in today's power transmission systems. The various protocols and network topologies used for protective relaying purposes are explained. Associated communication standards are outlined. The aim of this book is to provide background on the communication technologies used by protection system. Moreover, the rapid changing and development in relays principles as well as in their technologies are additional factors that oblige those people working in the field to expand and update continuously their knowledge. In this book, we shed light in the evolution of protective relays since the onset of electrical energy to currently. We try also to foresee the future prospects and trends in this area.

Available in PDF, EPUB and Kindle. Book excerpt: Written by two practicing electrical engineers, this second edition of the bestselling Protection of Electricity Distribution Networks offers both practical and theoretical coverage of the technologies, from the classical electromechanical relays to the new numerical types, which protect equipment on networks and in electrical plants. A properly coordinated protection system is vital to ensure that an electricity distribution network can operate within preset requirements for safety for individual items of equipment, staff and public, and the network overall. Suitable and reliable equipment should be installed on all circuits and electrical equipment and to do this, protective relays are used to initiate the isolation of faulted sections of a network in order to maintain supplies elsewhere on the system. This then leads to an improved electricity service with better continuity and quality of supply.

Book excerpt: Electric relays pervade the electronics that dominate our world. They exist in many forms, fulfill many roles, and each have their own behavioral nuances and peculiarities. To date, there exists no comprehensive reference surveying the broad spectrum of electric relays, save one-Electric Relays: Principles and Applications. This ambitious work is not only unique in its scope, but also in its practical approach that focuses on the operational and functional aspects rather than on theory and mathematics. Accomplished engineer Dr. Vladimir Gurevich builds the presentation from first principles, unfolding the concepts and constructions via discussion of their historical development from the earliest ideas to modern technologies. He uses a show-not-tell approach that employs nearly 1300 illustrations and reveals valuable insight based on his extensive experience in the field. The book begins with the basic principles of relay construction and the major functional parts, such as contact and magnetic systems. Then, it devotes individual chapters to the various types of relays. The author describes the principles of function and construction for each type as well as features of several relays belonging to a type that operate on different principles. Remarkably thorough and uniquely practical, Electric Relays: Principles and Applications serves as the perfect introduction to the plethora of electric relays and offers a quick-reference guide for the experienced engineer.
Download or read book Silent Sentinels written by Westinghouse Electric & Manufacturing Company and published by Westinghouse Electric & Manufacturing Company. This book was released on 1924-01-01 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: RELAYS have been aptly termed "silent sentinels." And they are silent sentinels. They stand on duty twenty-four hours a day, every day in the year, and— year in and year out. They guard thousands of dollars worth of property and equipment. They prevent service interruptions and costly shutdowns. They are really and truly the silent sentinels of the electrical industry. Automatic control is a reality. Supervisory control has been introduced. The inter - connection of systems is no longer an experiment. Service is now reliable and continuous. All of these are attributes of super-power— a new era in the electrical industry. And they were made possible through Westinghouse pioneering in the relay art. Not only has Westinghouse introduced most of the present-day relays, but this Company has also developed various schemes and methods of relay application. Westinghouse relays and relay practice have played an important role in the progress of the electrical industry. It is the purpose of Westinghouse to maintain and extend this leadership to meet the exacting requirements of the future.
