Excerpt from The Design of Static Transformers
The present treatise is exclusively of a practical nature. It constitutes, however, merely a brief introduction to the practical aspects of transformer design and construction. If the reader has not already acquired a knowledge of the theory underlying the subject, he could not do better than to study either Prof. Gisbert Kapp's "Transformers," or Prof. J. A. Fleming's "The Alternate-current Transformer." In spite of the ten years which have intervened since the publication of the last edition of the latter work, it still remains, in my opinion, one of the very clearest expositions of the theory of the transformer. My own work in this field, so far as it is set forth in the present volume, simply deals with the application to practice of the theory so admirably set forth by Profs. Fleming and Kapp in the excellent treatises to which I have referred. Although remarkably few books have been written on transformers, nevertheless there exists a fairly extensive literature on the subject, but it is in the form of articles and papers. Amongst the most noteworthy recent contributions may be mentioned the paper by Messrs. A. P. M. Fleming and K. M. Faye-Hansen, which was read in November, 1908, at the Institution of Electrical Engineers, and the paper read in June, 1909, by Mr. E. G. Reed, at the Thirty-second Annual Convention of the National Electric Light Association.
A perusal of my treatise entitled "Electricity" (Constable & Co., London, 1910), will assist to an understanding of the terms "power factor." "inductance," "reactance" and "impedance," if the reader is not already clear as to the meaning of these terms.
