| Abstract: | The paper analyzes the several major p arameters of the lightning current produ ced by the direct thunder between the cl oud and the earth, including prelusive c urrent, return current, contiguous curre nt and succeeding current, and the time they last. The electricity power, stab le electricity power, heat induct, wind pressure, and impulsive wave caused by t he thunder should be considered in the s afety coefficient selection when the spe cification of the aluminous lightning ro b is determined by using Newton heat equ ilibrium formula. The type of the ground line of the lightning rob for different mast materials is also given in this pa per. |
