A numerical calculation method is proceeded to investigate the effect of overhead line tower geometric constructions to the lightning shielding failure. This numerical calculation is based on the Leader Development Model of lightening [1–8] and the charge distribution in the leader channel is set as literature [6]. In this paper, the height and the separation distance of the ground wire was changed...
The shielding failure is the occurrence of a lightning stroke that bypasses the overhead shielding wires and strikes on the phase conductors. The accurate design to improve the shielding effect of transmission line to lightning is one of key problems in transmission line design. Some numerical analysis models for analysis of shielding failure performance were proposed and discussed, mainly including...
