Power System Relaying (Electronic and Electrical Engineering Research Studies: Lines and Cables for Power Transmission Series)

Written from the perspective of a practicing relay engineer, it is designed to introduce the basic theory and practical aspects of relaying and to remove the mystique surrounding this technology. Examines each element in the power system and in the protective relaying chain, their requirements plus the derivation of appropriate formulas. Includes a wealth of numerical examples which illustrate the philosophy underlying relay selection and settings and offers problems which characterize actual power system situations.
