This paper analyzes the lightning protection principle of lightning rods and overhead ground wires along with the major factors influencing their protection range. It is concluded that 1) all formulas dealing with the said protection rage at home and abroad are empirical formulas, for some key influencing factors can not be quantitated; 2) the difference of the protection range stipulated in various documents is the result of different permissible lightning strike probability; 3) absolutizing the protection range of lightning rods and overhead ground wires should be avoided.
