【Abstract】 In this paper, Mental-oxide arrests(MOA) used in 110 kV transmission lines to enhance the lightning withstanding level is studied, and some factors which influence the lightning withstanding level, such as wave shape of the lightning stroke, the tower grounding resistance, the length of span, the rating voltage of the arrestors and the stroke location of the transmission lines are analyzed, which provide reference to chose electrical parameters of the MOA used in the transmission lines.更多还原
