Analysis was made to 110~500 kV transmission line lightning tripping causes in Hangzhou area and according to the features of the area lightning activities, this paper laid down the corresponding anti-lightning reform countermeasures. Via adoption of anti-lightning measures as reforming grounding resistance as the main;additionally installing arrestors as the assistance, the anti-lighting level of pole tower was greatly lifted, which effectively prevents lines from winding lighting, reducing line lighting tripping rate.
