This book investigates the multifaceted problem of power quality within electrical power systems and machines. It addresses the root causes, observable effects, methods of modeling and measurement, and practical solutions for power quality disturbances. The text covers a wide array of issues, including nonsinusoidal waveforms, voltage sags and swells, harmonic distortions, and transient events, providing a thorough understanding for both theoretical and applied contexts.

The book is structured to serve as both an undergraduate/graduate course textbook and a professional reference, indicating a comprehensive and detailed approach to the subject matter. Its inclusion of application examples in common engineering software suggests a practical orientation alongside its theoretical foundations. The extensive list of references further points to its utility as a scholarly resource for in-depth study.
