Abstract :
Investigation of the effects of lightning discharges on the 220-kv transmission lines of the Pennsylvania Power and Light Company has been continued over a period of several years; results obtained during the perio 1931-33 are reported and analyzed in this paper. By the use of the ``distribution ratio method´´ of locating faults nearly all 220-kv faults causing line trip-outs were found quickly and positively correlated with time, dynamic current, lightning current, insulator flashovers, line construction, and tower footing resistance.
