The mechanical and electric characteristics of transmission lines

The object of this paper is to present in compact form the data and formulæ, together with their derivations, required for the determination of the mechanical and electric characteristics of transmission lines, together with a set of charts whereby the various mathematical operations involved may be accomplished rapidly and with the minimum effort. The treatment naturally falls under two headings, A — Mechanical Characteristics, and B — Electric Characteristics. Summaries of the working symbols and equations for Part A and Part B follow the general discussion under these heads.
