Book excerpt: Excerpt from The Design of Alternate-Current Transformers The invention of the alternate-current transformer some years ago led to the introduction of the system of high-tension distribution of electric energy for lighting purposes. The saving in the first cost of the copper mains being the chief advantage of the system in the eyes of the promoters, the question of the efficiency of this method of supply, except at full load, was not considered. Now, experience has shown that the cost of the annual supply depends largely on the efficiency of the transformers used, and that the loss at light loads is the most important factor in determining this cost. Hence the design of alternate-current transformers needs more careful attention as the demand for higher efficiency arises. I have endeavoured in the following pages to describe as simply as possible the principles involved in the construction of transformers on economic lines, both as regards first cost and power wasted when working. To the formulae deduced from these principles I have added several others which are useful when determining quickly the dimensions of the various circuits. To enable more to follow the reasoning, higher mathematics have been avoided, although this omission has necessitated the acceptance of certain well-known formulae without proof. The examples worked out and illustrated show the general procedure of designing transformers of different types to fulfil definite conditions.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Principles of Transformer Design A Book which deals exclusively with the theory and design of alternating current transformers is not likely to meet the requirements of a College text to the same extent as if its scope were broadened to include other types of electrical machinery. On the other hand, the fact that there may be a limited demand for it by college students taking advanced courses in electrical engineering has led the writer to follow the method of presentation which he has found successful in teaching electrical design to senior students in the school of Electrical Engineering at Purdue University. Stress is laid on the fundamental principles of electrical engineering, and an attempt is made to explain the reasons underlying all statements and formulas, even when this involves the introduction of additional material which might be omitted if the needs of the practical designer were alone to be considered. A large portion of Chapter II has already appeared in the form of articles contributed by the writer to the Electrical World; but the greater part of the material in this book has not previously appeared in print.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Design of Static Transformers It has been deemed desirable that the present work should deal with the fundamental principles of practical designing, but so soon as these principles have been assimilated, the reader should proceed to study carefully the many essential constructional details. A Bibliography of a considerable number of papers relating to static transformers is given at the end of Chapter I. In conclusion, I wish to acknowledge the work of my former assistant, Mr. Evelyn Good, who carried through many of the calculations, under my direction, and prepared a good many of the curves and diagrams. My assistant, Mr. C. Martin, compiled from my data certain portions of Chapters VIII. And IX. My thanks are due to the several manufacturing companies whose designs are described for their courtesy in providing me with the necessary information and for photographs and drawings.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Transformer Practice: Manufacture, Assembling, Connections, Operation and Testing The development of the alternating-current transformer dates back about 25 years. At that time very little was known re garding design for operation at high voltages, and the engineer of the present day can scarcely realize the difficulties encountered in the construction of the early transformers. The high-voltage transformer made long-distance trans mission work possible, and the increased distances of transmission stimulated the design of large transformers. In the early days of transformer development as many as 15 to 20 transformer secondary windings have been connected in series to facilitate the operation of a long-distance transmission system, the maxi mum rating of each transformer being not greater than 10 kw. However, a method of constructing large transformers has long been devised by which an enormous amount of power may be transformed in a single unit. Such designs embody principles of insulation for high voltages and various methods for maintain ing a low operating temperature. Ten years ago a 500-kilowatt unit was considered to be a large size of transformer. The history of ten years' development has shown a most interesting process of evolution: it has marked more than a tenfold increase in size up to the present day.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Electrical Machine Design: The Design and Specification of Direct and Alternating Current Machinery A study of design is of the utmost importance to all students, because only by such a study can a knowledge of the limitations of machines be acquired. The machines discussed are those which have become more or less standard, namely, direct-cur rent generators and motors, alternating current generators, syn chronons motors, polyphase induction motors, and transformers; other apparatus seldom offers an electrical problem that is not discussed under one or more of the above headings. The principle followed throughout the work is to build up the design for the given rating by the use of a few fundamental formulae and design constants, the meaning and limits of which are discussed thoroughly, and the same procedure has been followed for the several pieces of apparatus.
