II — Experience on a system with high ground resistance

FOR YEARS, lightning storms in the territory served by the Edison Electric Illuminating Company of Boston have been accompanied by numerous blown fuses, damaged and burned out transformers, and other troubles, all of which caused many outages to customers with consequent annoyance to them as well as expense to the company. This company distributes electrical energy in 40 cities and towns, embracing 650 square miles in and about the city of Boston. (See Fig. 6.) A total of 325,000 retail customers is supplied from 10,200 Standards Publication No. 108, “Ground Connections for Electrical Systems,” by O. S. Peters, June 1918.)
