Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Study of Phasing Transformers Evolution of the Transformer. As we wish to write of those discoveries which lei up to the invention of the transformer, we must go back to a time, old as compared with the modern development of electrotechnics. For the startinpoint of our observations we shall take Paraday, who, like Newton in mechanics lei the way in the domain of electricity, and whose name stands in the most intimate relations with all inventions for the mechanical production of the electric current, and therefore with the later development of electrotechnics. Paraday, 1831.The most important discovery for which we have to thank Faraday is that of induction. This discovery was made by him in the year 1831 and intimated to the philosophical world in a paper read on the 24th November 1831, appearing in the Transactions of the Philosophical Society in the year 1832. Paraday's first induction apparatus consisted of two coils of wire, the one being slid over the other. As he was passing the current from a battery through one of these, he made the discovery that each time the current of the coil was opened or closed an electromotive force was created in the second coil, which caused a short gush of current or induction current to flow, provide! the circuit of this coil was closed, as might be through a Galvanometer.

This book was released on 2015-07-03 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Determination of the Ratio of Transformation and of the Phase Relations in Transformers Usually the phase of the secondary is so nearly the reverse of the primary phase that the error with high power-factors would be insignificant, but with low power-factors a large error might be introduced, as may be seen by reference to the numerical examples given below. In view of these facts, it is thought desirable to publish the methods of measurement of these quantities in use at the Bureau of Standards. In the vector diagram, Fig. i, are shown the various quantities which go to determine the ratio of the transformer. The length of the vector is proportional to the maximum value of the quantity, and it is considered to be rotating uniformly in a counter clockwise direction. Its projection on a fixed diameter will then represent the instantaneous value of the quantity, assuming it to be sinusoidal. The angles between the vectors represent the phase-angles of the corresponding quantities. represents the magnetic flux linking both primary and secondary windings. It induces in the secondary winding an electromotive force E2 and in the primary winding an electromotive force in the same direction, but of different magnitude, fixed by the number of turns.

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.

Book excerpt: Excerpt from Transformers: Their Theory, Construction and Amplification, Simplified It has often been observed by almost every member of the electrical fraternity, that induction, and its out come, the transformer, is to the popular mind, the greatest mystery of the whole lighting system with which they come in contact. There is something tangible about the dynamo. Its movement, and the applied power are apparent. The lamp glows, and its action is appreciable, but the trans former remains to them an uncanny mystery. So too the average electrician whose training has long accustomed him to the management and applica tion of the electric current, finds in the transformer as a rule, more points regarding which his mind is hazy and uncertain, than in any other one piece of appara tus with which he has to deal.

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.
