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.

Overcurrent Relay Advances for Modern Electricity Networks explores how to optimize protection and improve system stability and resilience by implementing advanced overcurrent relays in highly dynamic renewable heavy power systems. This guide provides a foundation in relay functions and behaviors in current modern networks, particularly regarding renewable power sources and new electrical network structures such as microgrids. The work discusses the design and creation of protection schemes in smart grids and analyzes their impact on performance and security in protection systems. This practical book also presents a critical new coordination method for online applications. Reviews performance considerations and application challenges in optimizing overcurrent relays in future networks Provides mathematical and computational modeling scenarios for relays geared for application in future commercial equipment designs Describes how to adopt online protection systems by means of optimization algorithms for the adjustment and coordination of relays Includes pseudocodes of routines designed to support readers who are implementing or analyzing these systems Outlines a demonstrative virtual relay to execute programming operation and optimize coordination of relays

As modern protective relays become increasingly more powerful and complex, many relay testers continue to use test procedures and philosophies that are based on previous generations of relays and their limitations. Modern relays have very different characteristics that require a different testing philosophy to ensure that they will operate when required. The Relay Testing Handbook: Understanding Digital Logic explains the different forms of relay logic used in modern microprocessor based relays. Each type of relay logic is described in detail with practical examples to demonstrate how relay manufacturers use common relay logic principles applied with different style interfaces such as: Individual element schemes (General Electric SR and Beckwith Electric Company relays) Binary relays (Alstom and Siemens relays) Arithmetic (math) schemes (Schweitzer Engineering Laboratories relays) Logic schemes (General Electric UR relays) Use the practical examples outlined in this volume to help you: Understand and use logic gates such as AND, OR, NOT, NOR, NAND, and moreUse logic comparators and timersConvert relay settings from one logic format to anotherConvert logic schemes into DC schematics to help understand and commission logic systemsUnderstand the protective relay logic used in nearly every in-service relay today This book is included in the hardcover book The Relay Testing Handbook: Principles and Practice, or it can be ordered by itself as a soft-cover book, Adobe Acrobat PDF digital download, or both.

The Relay Testing Handbook was created for relay technicians from all backgrounds and providesthe knowledge necessary to test most of the modern protective relays installed over a widevariety of industries. Basic electrical fundamentals, detailed descriptions of protective elements,and generic test plans are combined with examples from real life applications to increase yourconfidence in any relay testing situation. A wide variety of relay manufacturers and models areused in the examples to help you realize that once you conquer the sometimes confusing andfrustrating man-machine interfaces created by the different manufacturers, all digital relays usethe same basic fundamentals and most relays can be tested by applying these fundamentals.This package provides a step-by-step procedure for testing the most common differential protectionapplications used by a variety of manufacturers. Each chapter follows a logical progression to helpunderstand why differential protection is used and how it is applied. Testing procedures are describedin detail to ensure that the differential protection has been correctly applied. Each chapter uses thefollowing outline to best describe the element and the test procedures.1. Application2. Settings3. Pickup Testing4. Timing Tests5. Tips and Tricks to Overcome Common ObstaclesWe will review techniques to test differential relays with 3 or 6 channels so that readers can test nearlyany differential application with any modern test set.
