Transformers: Theory

The electrical power industry has a need for a book on transformers with emphasis on practical applications. This book will enable practicing engineers understand the finer nuances of theory, design and practice followed by the present electrical industry experts. The book illustrates the current practices in the industry used by different manufacturers by considering case studies that will illustrate the new trends encountered in partial discharge measurements for extra high voltage transformers using acoustic methods, design of five-limb cores using finite element analysis and canned software. An economical optimum choice of a transformer design is illustrated using computing methods that generate an 18-slot design to vary flux density, current density and other important aspects of all active materials used in the manufacture of electrical power transformers. Many myths about transformer design procedures are removed using simple and easy to understand logical steps.
