【正文】 d resistance while a smaller part goes down the line and to ground through the adjacent tower tower rises in voltage due to the current 1I though the resistance 1R to a value whice is 111 RIU ? Approximately this voltage appears between the tower and the power conductor (which was not struck).If this voltage is less than that required to cause insulator flashover， no trouble by this method is improved by using two carefully placed ground wires and by making tower footing ground resistance of low value. The lightning record of lines supported on towers 80 to 90 feet tall substantiates the simple theory of line protection just poorer record of lines on towers over 100ft in height indicates that other factors， perhaps the in
