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.
