Shape Proposal and Electric Field Distribution of Horizontal Lightning Conductor

Abstract

Horizontal lightning conductor is installed horizontally on the top or side of the building. It uses specific materials and wires or rods of minimum thickness. In the horizontal conductor system, a horizontal conductor is laid on top of the building to be protected and absorbs the lightning through it. And the lightning current is safely discharged to the earth through the conductor connecting this to the ground. The starting point of the discharge current of the lightning strikes depends on the sectional shape of the horizontal conductor. In this paper, a new shape is proposed through electric field analysis in order to find the optimum shape that can lower the discharge start voltage according to the sectional shape of the horizontal conductor. Two - dimensional electrostatic field analysis was carried out for the electric field analysis, and the maximum electric field was analyzed at the upper part of the horizontal conductor for comparative analysis. This study is considered to be helpful in designing or constructing horizontal conductors.
