Book excerpt: The Bible is laden with stories of those who've carried the baton before us, who've stumbled,who've persevered. It's equally laden with stories of God's chosen people falling-away from theirfaith - often in the space of just a few short years.So is Christianity itself in peril? "Of course not," Shamblin notes, "but under the rightcircumstances, it is endangered in any given region of the world. Consider that, just a generationand a half after John Lennon outraged the West by quipping that the Beatles were 'bigger thanJesus,' Europe's percentage of practicing Christians is in the single digits."In The Relay, Shamblin catalogs the comparative successes and failures of nine individuals inpassing-along their faith to the next generations - from the father of all failure (Adam) to theultimate Spirtual Rags To Riches success (Paul). At the center of his book, not only thematicallybut literally (chapter six of eleven) is Jesus Christ, whose followers who took "the race" to a wholenew level, and a whole new arena.While a relay makes for an apt metaphor for passing-along our faith, Shamblin concludes, ourgoal as Christians is not to win a race, but to win the world. More than a message of profoundaffirmation, The Relay is a triumph of practical How To advice for anyone looking to take theirown journey with the Lord to the next level - and beyond.

Available in PDF, EPUB and Kindle. Book excerpt: This book was created for relay test technicians and provides the knowledge and skills necessary to test most of the modern protective relays installed over a wide variety of industries. Basic electrical fundamentals, detailed descriptions of protective elements, and generic test plans are combined with examples from real life applications to increase your confidence in any relay testing situation. A wide variety of relay manufacturers and models are used in the examples to help you realize that once you conquer the sometimes confusing and frustrating man-machine interfaces created by the different manufacturers, all digital relays use the same basic fundamentals and most relays can be tested by applying these fundamentals.By the end of this book, you will have the information you need to: Evaluate relay applications Review, understand, and compare the relay settings to the application Create a test plan Test the most commonly applied elements:Instantaneous Overcurrent (50)Inverse Time Overcurrent (50)Directional Overcurrent (67)Undervoltage (27)Overvoltage (59)Over/Under Frequency (81)Differential (87) (With three of six current channels)Line Distance (21) Evaluate the test results Provide comprehensive test results and documentationEach chapter is a self contained unit and the chapters are organized in a logical progression of knowledge to allow readers from different skill sets to focus on or skip to the sections they need without wasting time reading through information they already know.

Available in PDF, EPUB and Kindle. Book excerpt: The Relay Protection of High Voltage Networks presents the theoretical aspects of relay protection of high-voltage electrical networks. This book covers a variety of topics, including sequence networks for complex asymmetrical states, vector locus method, theories of symmetrical component filters, and power directional devices. Organized into 10 chapters, this book begins with an overview of the use of sequence networks. This text then examines the relay protection of high-voltage networks with three-phase and single-phase tripping. Other chapters consider the principles of auxiliary devices, which serve for the selection of the faulty phase and for preventing the incorrect operation of protective gear during swings and for faulty conditions in the secondary windings of voltage transformers. The final chapter deals with the stability of parallel working of power stations in a system. This book is a valuable resource for engineers, student, research workers, and readers specializing in the field of relay protection.

Available in PDF, EPUB and Kindle. Book excerpt: Improve Failure Detection and Optimize Protection In the ever-evolving field of protective relay technology, an engineer’s personal preference and professional judgment are as important to power system protection as the physical relays used to detect and isolate abnormal conditions. Invaluable Insights from an Experienced Expert Protective Relay Principles focuses on probable power system failure modes and the important characteristics of the protective relays used to detect these postulated failures. The book presents useful new concepts in a way that is easier to understand because they are equally relevant to older, electromechanical and solid-state relays, and newer, more versatile microprocessor-based relays. It introduces the applications, considerations, and setting philosophies used in transmission-line, distribution-line, and substation applications, covering concepts associated with general system operations and fault detection. Topics include relay load limits, cold load pickup, voltage recovery, and arc flash. The author also delves into the philosophies that engineers employ in both urban and rural areas, with a detailed consideration of setpoint function. Analysis of Key Concepts That Are Usually Just Glossed Over This versatile text is ideal for new engineers to use as a tutorial before they open the instruction manuals that accompany multi-function microprocessor-based relays. Guiding readers through the transient loading conditions that can result in relay misoperation, the author elaborates on concepts that are not generally discussed, but can be very helpful in specific applications. Readers will come away with an excellent grasp of important design considerations for working with overcurrent, over- and undervoltage, impedance, distance, and differential type relay functions, either individually or in combination. Also useful for students as a textbook, this book includes practical examples for many applications, and offers guidance for more unusual ones.
