Abstract
With the introduction of extra-high-voltage transmission lines, various abnormal transient conditions are particularly significant, and a practical means of studying such phenomena is of primary concern to the electrical utility engineer. A method of simulating transmission lines utilizing the electronic differential analyzer is described. The appropriate form of the traveling-wave equations is presented whereby a completely general computer setup is realized suitable for any kind of line-terminating conditions. The simulation was achieved by constructing a multiple-channel pure transport delay time unit. Several examples of practical application are presented in which overvoltages are determined due to transmission-line switching surges.Keywords
