The improved electric geometrical model is proposed
and some on-site accidents are successfully explained
which are difficultly commented by EGM.With such model the effect of tower structure
lightning current amplitude
angle of the lightning incidence
as well as the ground angle on the shielding failure rate are analyzed.It is concluded that large lightning current can stride across lightning conductors to strike conductors under certain conditions in mountain areas.
