Abstract

This paper presents a methodical approach, suggestions and information to design 400 kV transmission lines, check which types of towers, conductors and insulators are suitable to use based on wind velocity. as well as calculate the effect of wind on L12 tower top geometrics, and keep the probability of flashover very low. In this project, weather and climate are considered in the design of overhead lines. The purpose of this paper is to determine the clearances necessary for a 400 kV line to withstand high wind velocity, and ensure that conductors have to maintain the clearances under lightning, switching and TOV (temporary over voltage). Excel and Visio are used to analyse the results and plot them, in order to find the swing angle of movement of the insulator and conductor, and the minimum clearances produced under certain wind speed. Finally, the return period per year and the probability of conductor infringes the clearances per year are calculated.
