This book has been written with the object of giving a thorough exposition of the scientific principles upon which the action of a transformer is based, of the application of these principles to the design of such apparatus and of their construction and uses. Much material has, of course, been collated from various sources, but much of the matter is original, and is here published for the first time. In particular, an entirely new method of designing by the second author is given in Chapter X., which eliminates the series of trial designs which have hitherto been customary, and leads to a good design straight away. This method is so simple and direct that even an inexperienced designer can easily get at once a preliminary design to meet any given conditions with full confidence that he is making the best use of the material employed. The method also leads to very definite statements as to the relative value of difierent types of transformers, or different materials, and as to the effects of the several variables on the cost. This chapter has caused a delay of over eighteen months in the publication of the book, as all the rest was in type before the clue was obtained which enabled the method here given to be evolved. The authors have aimed at uniformity and simplicity in the symbols used throughout the book, and with this end have adopted the principle of always using the same symbol for any quantity, and of using that one for no others. When necessary, distinction is drawn between different quantities of the same kind by using suffices; at first sight this sometimes appeals cumbersome in places, but when the method becomes familiar this feeling disappears, and the saving by its use is enormous.(Typographical errors above are due to OCR software and don't occur in the book.)About the Publisher Forgotten Books is a publisher of historical writings, such as: Philosophy, Classics, Science, Religion, H
