![]() Index Terms- 400kV overhead power line, wind impact on L12 tower, design top geometries. Some examples of uniform transmission lines are coaxial cables, twisted-wire pairs, and parallel-wire pairs. That is, the conductor shape, size, and spacing are constant, and the electrical characteristics of the conductors and the material between them are uniform. Finally, the return period per year and the probability of conductor infringes the clearances per year are calculated. A uniform transmission line is one whose geometry and materials are uniform. 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. As a first step, the potential of the conductor strip is set to V0 and Laplace’s equation is solved using an EM simulator for the electrostatic potential everywhere in the dielectric. 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). The procedure described is used in many EM computer programs to calculate the characteristics of transmission lines. In this project, weather and climate are considered in the design of overhead lines.

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. One of the most basic parameters of a transmission line is zo, its characteristic impedance. ![]()
