One of the critical elements to enable these higher data transmission speeds is the transmission line performance. Index Terms- 400kV overhead power line, wind impact on L12 tower, design top geometries. Anyone in attendance at DesignCon 2023 knows that 224 Gb/s PAM4 signaling is in full development, but there is still some time yet before it is actively deployed. One of the most common types of transmission line, coaxial cable. Black dots represent electrons, and the arrows show the electric field. Finally, the return period per year and the probability of conductor infringes the clearances per year are calculated. Schematic of a wave moving rightward down a lossless two-wire transmission line. 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. The cross-sections of these lines are shown in Figure 1. In this section, zo is calculated for four common transmission lines coaxial, twin-lead, parallel plate, and microstrip. zo depends upon the geometry and the material of the transmission line. zo depends upon the geometry and the material of the transmission line. One of the most basic parameters of a transmission line is zo, its characteristic impedance. 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). One of the most basic parameters of a transmission line is zo, its characteristic impedance. In this project, weather and climate are considered in the design of overhead lines. Transmission line modes are field configurations supported by the structure. as well as calculate the effect of wind on L12 tower top geometrics, and keep the probability of flashover very low. First, let’s talk a little bit about transmission line modes. On this page we provide the necessary details for some standard. 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. To calculate the field from a power line, you need to know the geometry of the conductors.
