Excerpt from The Elements of Electrical Transmission: A Text-Book for Colleges and Technical Schools
In preparing the material for this book, it has been the author's aim to present those things which should be grouped and articulated in order to afford an elemental study of the very broad subject of the generation, transmission, distribution and utilization of power by electrical processes. The title of the work only partially covers this field, but was chosen with a view to brevity and convenience. In fact, our language needs some modest word for so large a subject.
Necessarily, the material available far exceeds the capacity of any single volume, but the attempt is made to provide a working text-book which may serve as a more or lees complete course, depending upon the amount of time available for the subject. It is hoped that it may serve as an outline for even an extended course, supplemented always by that most important source, the teacher. Nevertheless, the book will probably stand or fall as an elementary text-book, which is all that it desires to be.
It is proper to discuss subjects which have been presented in other books, because they are important features. It has also seemed wise to provide certain discussions not elsewhere available because, sooner or later, the student feels the need of them. Under this head would come the matters of self-induction and capacity of polyphase circuits as derived from single-phase circuits, line calculations, standing waves, traveling waves, curve calculations, etc. Further comment might be made upon each of these topics and it seems necessary to speak particularly of the methods presented in making line calculations. Here, there are given several processes, each used more or less commonly. They are all presented in detail in order that contrasts may be made and the simplicity of the series approximation emphasized.
As is pointed out, the matter of corona is not analyzed minutely. It, rather, has been simplified as much as is consistent with the fundamental conceptions of the phenomenon.
