Calculation of Lightning-Induced Voltages on Overhead Multiconductor Systems

A computer program has been developed for numerically analyzing lightning- induced voltages on multiconductor lines. Thi. s program can be used to clarify the effects of lightning arresters and overhead ground wires on lightning-induced voltages, which has not before been possible, anid is potentiaLly of great uise in the lightning-resistant design of distribution lines. The results obtained with this numerical analysis program were compared to the results from an analog simulation using a 1:200 scale model, and found to be in good agreement, demonstrating the usefulness and validity of the program.
