【正文】 lators and does the pole to voltage set up on the line may be that necessary to flash over this path to ground. On the occurrence of a stroke， lightning clouds do not discharge in zero ， the stroke current rises from zero value to maximum value in a few microseconds and is pleted in a few hundred microseconds. Direct lightning strokes to lines are of concern on lines of all voltage class， as the voltage that may be set up is in most instances limited by the flashover of the path to ground， increasing the length of insulator strings merely permits a higher voltage befoe flashover most generally accepted method of protection against direct strokes is by use of the overhead ground simplification only one ground wire and one power
