Considering the factors such as randomness of natural lightning locus and the coexistence of primary and secondary leaders, it is necessary to lead in the concept of dynamic lightning protection shielding angle. It is suggested that the angular bisector of practical protective angle formed by ground wire or earth pin in UHVAC transmission line and conductor should be aligned with the direction of lightning leader as well as the ratio of vertical span to horizontal span and the impact of wind speed should be considered.
