Ships in 6-8 business days.
This hardback book includes most of the volumes in the The Relay Testing Handbook series and includes: Electrical fundamentals; Relay testing fundamentals; How to translate digital logic used by... More > relay manufacturers into familiar concepts; and Best practices for creating and implementing test plans. Entire chapters are dedicated to the most commonly used protective elements including: Overvoltage, undervoltage, and frequency (59/27/81); Time, instantaneous, and directional overcurrent (51/50/67); Simple and transformer differential (87) testing with three or six current channels; and Line distance (21) testing using realistic test plans to minimize setting changes. Each protective element chapter includes: A description of operation written for a relay tester, not for a design engineer; Step-by-step test techniques that maximize your effectiveness and efficiency; Realistic examples from various relay manufacturers and models.
