Available in PDF, EPUB and Kindle. Book excerpt: 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: Testing Overcurrent Protection (50/51/67) provides step-by-step procedures for testing the most common overcurrent protection applications. This volume is designed to help you understand and test: Instantaneous overcurrent protection (50) Inverse time overcurrent protection (51) Directional overcurrent protection (67) Each chapter explains the following topics for each element with realistic, practical examples and detailed instructions: Understanding the application Determining which settings are most important Recommended steps to correctly plan, perform, and evaluate pickup tests Recommended steps to correctly plan, perform, and evaluate timing tests Preventing interference from other settings inside the relay Tips and tricks to overcome common obstacles 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: 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.

Download or read book The Relay Testing Handbook written by InterNational Electrical Testing Association. Conference and published by . This book was released on 2012 with total page 629 pages. 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. We also provide packages for technicians who are looking for specific information only. These packages can be downloaded in pdf format for easy viewing and printing as they become available.

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.
