The electric utility's increasing use of power factor correction capacitor banks and the industry's widespread application of power-electronic converters have set the basis for, recently, paying considerable attention to the issue of power system harmonics. Aiming at a better understanding of power system harmonics, this text presents a discussion of this issue, providing a quantitative analysis when possible. Pertinent equations are developed. 80 practical case studies based on real-life work experience come with the text. These are analysed providing the results and commenting on the output. Furthermore, 80 end-of-chapter problems are provided. A detailed solution manual is available. The book can be used as a textbook for undergraduate and graduate students, in short-courses offered by consultants and institutes, as well as a tutorial, reference, or self-study course for practising engineers in the industry and electric utilities.Wakileh, George J. is the author of 'Power Systems Harmonics Fundamentals, Analysis, and Filter Design' with ISBN 9783540422389 and ISBN 3540422382.
