Excerpt from Transformers for Single and Multiphase Currents: A Treatise on Their Theory, Construction, and Use The object of the present book is to enable the reader to judge the design of transformers and to design such appara tus for himself. The mathematical treatment of the subject has been kept as short and as simple as possible. I am well aware that through the omission of many theore tical considerations which were not immediately pertinent to the practical object I had in view, my book, considered as a scientific treatise on transformers, is incomplete. I have omitted to include detailed researches on the in¿uence of the shape of current and EM waves on hysteresis loss, I also have omitted the analysis of such waves by Fourier's series, and generally the analytical treatment of problems connected with transformers. These are sins of omission for which I plead the indulg ence of the reader, on the ground that my book is not intended for mathematicians or physicists, but for engineer ing students and practical engineers, whose object must always be to obtain a maximum of practical success with a minimum expenditure of mental labour.
