Reflecting new technologies and the latest practices in the field, ELECTRICAL TRANSFORMERS AND ROTATING MACHINES, 3E combines a current, comprehensive explanation of theory with practical applications of electrical machines. The text begins with a study of magnetism and magnetic induction, single-phase isolation transformers, current transformers, and autotransformers. A unit on three-phase power covers basic connections and calculations before proceeding into transformers. Throughout the text, practical experiments enable readers to reinforce theory with hands-on application. The Third Edition also includes an all-new Instructor Resource CD with PowerPoints, Image Library and ExamViewTM test bank generator. With its unique combination of transformers and motors, Electrical Transformers and Rotating Machines, 3e is an excellent resource for electrical students and practitioners alike.
