【正文】 conductor are shown. The ground wire is placed above power conductor at such a positon that practically all lightningstroke paths will be to it instead of to the power current then follows to the ground， most of it passing through the tower footing ground 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
