In recent years Fundamentals of Electrical Transformer: Principles, Designs & Applications is being used extensively in Electrical Engineering, Microprocessor, Electrical Drives and Power Electronics research and many other things. This rapid progress in Electrical & Electronics Engineering has created an increasing demand for trained Electrical Engineering personnel. A transformer is a passive electrical device that transfers electrical energy between two or more circuits. A varying current in one coil of the transformer produces a varying magnetic flux, which, in turn, induces a varying electromotive force across a second coil wound around the same core.

The demand for power and distribution transformers will rise steeply because of huge development, as will the emphasis on quality and performance. The quality of a transformer is determined by its design, as well as the persons, machinery, and materials used. This book is a practical guide to distribution transformer design, manufacturing process control, installation, erection, commissioning, and maintenance. It also includes failure analysis and solutions for extending the life of transformers.

This book is intended for the undergraduate and postgraduate students specializing in Electronics Engineering. It will also serve as reference material for engineers employed in industry. The fundamental concepts and principles behind Electrical Transformers are explained in a simple, easy- to- understand manner. Each chapter contains many solved example or problem which will help the students in problem solving and designing of Transformer.

I do hope that the textbook in the present form will meet the requirement of the students doing graduation in Electronics & Communication Engineering, Electronics & Instrumentation Engineering and Electrical & Electronics Engineering. I will appreciate any suggestions from students and faculty members alike so that we can strive to make the textbook more useful in the edition to come.
