【Abstract】 For transmission lines,the rate of lightning striking against poles directly affects the calculation of lightning trip-out rate.The former has not only relations to topographic features, height and structure of poles or towers but also to amplitude and probability of lightning-current. According to the rate recommended by the"code",the mean rate of lightning striking against poles of transmission lines is discussed with an electrogeometric model.更多还原
