Excerpt from Transmission Line Formulas for Electrical Engineers and Engineering Students

The first method, which is described in Chapter III, is in the form Of a chart which gives the regulation or voltage drop of a line, and which also shows directly the required size of conductor for given conditions.

In Chapter IV are given formulas for distribution lines and transmission lines only a few miles long. These are extended in Chapter V by means of the constant K to apply to transmission lines of any length in ordinary practice.

For purposes of checking different formulas, and for the calculation of extremely long and unusual lines, the fundamental formulas of transmission lines are expressed by rapidly converging series in Chapter VI. While these series require much more arithmetical work than the K formulas, they will give the exact results to any degree of accuracy desired. The method of convergent Series in volves the use of complex numbers, that is, numbers in which j terms appear. They are easier to handle, however, than logarithms, sines and cosines of angles, or hyperbolic functions, and therefore the use of these other mathematical functions has been avoided.
