Analysis of the Electric field of the 1200kv power transmission line using the Finite Element Method

With rapid industrial development and flourishing population, power demand is increasing rapidly. UHV power line is one of the ways to meet this increasing demand. 1200kv UHV transmission line, is India's forthcoming project to tackle this situation. Right Of Way (ROW) is one of the major concerns with transmission lines. An electric field is one parameter to define ROW. In this paper, electric field of three configurations of the 1200kv line is calculated by the Finite Element Method. FEM is used to solve partial differential equations. Calculations have been done by taking a case with the minimum ground distance of conductors of lines. Plotted results are compared with ICNIRP standards and safety limits defined. Biological effects of electric field on people, animals, and plants are also discussed.
