ABSTRACT: Expansion of power grid scale and shortage of KEY WORDS: AC and DC transmission lines hybrid-erected
corridors for transmission lines make the hybrid erection of AC on the same tower; improved electro-geometric model;
and DC transmission lines on the same tower possible under shielding failure; lightning protection performance
some special conditions. In view of that the shielding failure is
