500			_aThis thoroughly revised and updated edition presents a rigorous and comprehensive treatment of transformers and more common types of rotating electrical machines types. Each chapters begins with rudimentary concepts and is so developed, that an average student can easily comprehend it. Salient Features In-depth coverage of transformers, d.c. Machines, 3-phase synchronous and induction machines. Highlights that electrical machines operate on the same basic principles. Devotes a chapter on electromechanical-energy-conversion principles and another on d.c./a.c. Machine windings. Drive aspects and applications are discussed for each machine type. Clearity of presentation is enhanced by illustrative figures and examples selected from questions-papers of important Universities, IAS, IES and GATE. Includes numerous problems, conceptual questions and objective-type questions (with answers) to help the reader master the basic concepts. This edition also includes: electrical machinery overview, energy efficiency and resent advances; 3-phase transformers; 3-phase induction generation; appendices on magnetic circuits, 3-phase circuits and short-answer type questions. All these features contribute towards making this book and ideal text for undergraduate students of degree classes. Practising engineers, through self-study, will also find this volume useful to them.
