Abstract :
BY TAKING ADVANTAGE of knowledge gained from a 20-yr statistical research investigation of lightning protection for distribution circuits (Fig. 1), it appears possible to reduce the number of transformer troubles caused by lightning in Chicago to less than one case of trouble per year per thousand transformers in service. This article presents some of the later results of that 20-yr study.
