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... More > practical examples to demonstrate how relay manufacturers use common relay logic principles applied with different style interfaces such as: Individual element schemes (GE SR and Beckwith 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 more; Use logic comparators and timers; Convert relay settings from one logic format to another; Convert logic schemes into DC schematics to help understand and commission logic systems; Understand the protective relay logic used in nearly every in-service relay today Get more information at http://relaytraining.com/< Less
THE RELAY TESTING HANDBOOK #1: Electrical Fundamentals for Relay Testing By Chris Werstiuk
Paperback: $23.95
Prints in 3-5 business days
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... More > their limitations. Modern relays have very different characteristics that require a different testing philosophy to ensure that they will operate when required. As the first of The Relay Testing Handbook series, Electrical Fundamentals for Relay Testing contains the underlying electrical theory that all relay testers should understand. This information provides a foundation that all other handbooks in the series use when describing the most common protective elements, how they function, and the most effective and efficient procedures used to test them. Even experienced relay testers can benefit from having this manual on hand as a quick reference when facing an unfamiliar relay testing situation.
