This fourth edition of a bestseller covers the technological fundamentals of power system protection. Featuring refinements and additions to accommodate recent advances, the text describes analysis of protective systems during system disturbances and examines how regulations impact the way protective relaying systems are designed, applied, set, and monitored. Containing an expanded discussion of intertie protection requirements at dispersed generation facilities, it explores smarter, more flexible protective systems yet provides practical information on an array of equipment vintages to reflect the state of power systems today.

Emphasizing a practical conception of system unbalances, basic circuits, and calculations, this work presents the foundations of symmetrical components with a review of per unit (percent), phasors, and polarity.
