Excerpt from The Alternating Current Transformer

The following pages originated from a course of University lectures. It is hoped that the book will be of use to the engineer and general reader. Some knowledge of elementary alternating currents is presupposed.

I have found that the student who grasps the theory of the transformer has little difficulty with the more complicated actions and reactions taking place in the induction motor, and is also helped in his study of synchronous apparatus.

Chapters I and II are merely introductory. Chapters III to V, carefully studied, should give the reader a thorough knowledge of the transformer. The tests in Chapter VI should be carried out by the student on a few commercial types. The method of design in Chapter VII is offered as a probable improvement over that usually given in text books.

I wish to thank the manufacturers for the loan of cuts used in Chapter X.

Thanks are also due the publishers who have maintained their reputation for sparing no effort or expense to make the book mechanically as perfect as possible. I am indebted to Mr. A. S. Kalenborn for reading proofs.
