An unusual number of flashovers due to lightning have occurred on the 138-kv lines of Commonwealth Edison Company on a relatively new type of 138-kv double-circuit tower designed for only one overhead ground wire. Calculations based on the most recen

Lightning flashover trip-out rate for 138-kv double circuit towers designed for one ground wire is far in excess of rate anticipated by Commonwealth Edison Company when installed in 1954. Results of studies are presented on the cause of these trip-ou

When the ground wire on top of a transmission-line tower is struck by lightning the potential of the ground wire and the tower top is raised above the potential of ground. Because of electro-magnetic and electrostatic coupling between the ground wire

THE COMMONWEALTH Edison Company operates a 138-kv and a 230-kv overhead transmission system in northern Illinois. Prior to 1954, most of the 138-kv circuits were carried on double circuit steel towers designed for two overhead ground wires. A typical
