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.
