Paperback. Condition: New. Print on Demand. This book is a straightforward and comprehensive account of the alternating current transformer, a device that transfers power through space without relative motion between the two coils. The author begins by reviewing the fundamental principles of the magnetic circuit and the laws of magnetic induction. He next takes up the effects of the current in one coil upon the other, and develops equations that describe the secondary e.m.f. induced and the counter e.m.f. on the primary. The graphical representation of pressure relations is then discussed, and the author shows how to determine the regulation of transformers for any load and for any power factor. The final chapter deals with the efficiency of transformers, and the author provides a method for calculating the all-day efficiency of a transformer operating on a variable load. This book is a valuable resource for anyone who wants to understand the operation of transformers, and it is also a useful reference for electrical engineers.
