Excerpt from Transmission Line Formulas for Electrical Engineers and Engineering Students
The object of this book is to compile a set of instructions for engineers, which will enable them to make electrical calculations for transmission lines with the least possible amount of work.
The chart and working formulas have for the most part been developed independently by the author. Where the same or similar methods have been previously published, the fact is generally stated in the footnotes, but it has not been found possible to make these references absolutely complete.
The second part of the book is for reference and contains the derivation of the principal formulas used in connection with transmission lines. As many recent articles on transmission lines make use of formulas which are only roughly approximate, or are even incorrect, a reliable collection of formulas, with the method of obtaining them, should be found valuable.
It should not be presumed, because the second part of the book requires the use of the integral calculus, that the working formulas will require a knowledge of higher mathematics. The first five or six chapters are complete in themselves, and are planned for the use of those who have an ordinary acquaintance with alternating-current calculations.
