Excerpt from A Study of the Transformer Magnetic Circuit The alternating current transformer has opened up and made possible the development of a branch of electrical industry which a few years ago would have seemed impossible. Perhaps the m st striking illustrations of electrical development along the line referred to above are: the generation of electric power at Niagara, and its subsequent economical transmission to Buffalo, and the performance of the Fresno plant in California. In this latter, power is developed by a water fall and transmitted to Fresno, a distance of thirty five miles. Step up transformers are used at the generating end. The line tension in both cases is about eleven thousand volts. Step down transformers are used at the distributing end.

Excerpt from The Magnetic Circuit This book, together with the companion book entitled The Electric Circuit, is intended to give a student in electrical engineering the theoretical elements necessary for the correct understanding of the performance of dynamo-electric machinery, transformers, transmission lines, etc. The book also contains the essential numerical relations used in the predetermination of the performance and in the design of electrical machinery and apparatus. The whole treatment is based upon a very few funda mental facts and assumptions. The student must be taught to treat every electric machine as a particular combination of electric and magnetic circuits, and to base its performance upon the fundamental electromagnetic relations rather than upon a sepa rate theory established for each kind of machinery, as is some times done. The book is not intended for a beginner, bit for a student who has had an elementary descriptive course in electrical engi neering and some simple laboratory experiments. The treat ment is somewhat different from that given in most other books dealing with magnetic phenomena. It is based directly upon the circuital relation, or interlinkage, between an electric current and the magnetic flux produced by it. This relation, and the law of induced electromotive force, are taken to be the fundamental phenomena of electro - magnetism. No use what ever is made of the usual artificial concepts of unit pole, magnetic charge, magnetic shell, etc. These concepts of mathematical physics, together with the law of inverse squares, embody the theory of action at a distance, and are both superfluous and misleading from the modern point of view of a continuous action in the medium itself.

Excerpt from Transformer Characteristics The object of this investigation was to determine the various characteristics of the new type B form K General Electric transformer, when operated on both single and three-phase circuits under various conditions. The magnetic circuit of the transformer, which because of its shape might be called either a core or shell type, is made of a new grade of silicon steel having such physical qualities that the core loss is small.

Excerpt from Electric and Magnetic Circuits In the preparation of this work the author has received much assistance from the classical works and lectures of prominent electrical engineers and the technical press, and desires to acknow ledge his indebtedness to these authorities for the many ideas which have enabled him to prepare the following chapters. He has also to express his thanks to His Majesty's Stationery Office for permission to use the table of logarithms and anti-logarithms given in the appendix. As it is almost impossible in the first edition of a book of this nature to detect every slip which may occur during its preparation the author requests his readers who may detect any error or ambiguity to kindly notify him of the same so as to make the book as reliable as possible.

Excerpt from The Alternate Current Transformer in Theory and Practice, Vol. 2: The Utilization of Induced Currents The superiments (sampson's Annals, Vol. I., p. This was published in October, 1836. W. Sturgeon did not appear at this time to have been acquainted with Faraday's Ninth series of Electrical Researches; but after repeating mostof Henry's experiments, and adding some of his own, he arrived at the conclusion that the action of the spiral conductor in creating a shock was due to the collapse of the magnetic lines of force.
