Review quote

"… a very good contribution that covers many aspects of power systems and components. … I strongly believe that this book will be interesting for students and professionals in electrical power engineering."—Dr. Dipl.-Ing. M. Popov, Delft University of Technology (TU Delft), Netherlands"… provides an important resource for engineers, instructors, applied researchers, and students in the field of power engineering. … This well-written book offers broad coverage of important issues, operating concepts, and control techniques commonly addressed in most textbooks regarding power systems."—Dr. Chao-Tsung Ma, Department of Electrical Engineering, CEECS, National United University, Miaoli City, Taiwan "... a very good choice as a complete reference for power systems. Readers will find it worthwhile for their collections and self-reading material."—Prof. R. P. Maheshwari, Department of Electrical Engineering, Indian Institute of Technology, Roorkee "This book offers a simplified and summarized presentation of the majority of topics related to electric power systems. Sadhu (Indian School of Mines) and Das (Burdwan Univ., India) review and briefly discuss the foundations of a particular area in each of the book's 20 chapters. The first four chapters are an overview of basic concepts and terminologies employed in power systems engineering. The next six chapters focus on power overhead transmission lines and underground cables. They also cover issues related to transmission lines, such as corona and electrical insulation. Electric power distribution systems, earthing, and substations are presented in separate chapters. The book goes on to discuss elements of power system protection, including relays, circuit breakers, and fault analysis. Concluding chapters deal with power system stability and load flow. The authors have reduced the mathematical and physical complexities that one may encounter in each of these topics as much as possible, allowing the general reader with some background in power systems to benefit from the book. The worked examples and end-of-chapter questions are very helpful for understanding the material."—CHOICE, July 2016 Issue  show more
