Analysis of Electromagnetic Fields of 1200kV UHV-AC Transmission Lines

This paper presents the rigorous analysis of electric and magnetic field of 1200 KV, AC transmission line, India's most prestigious forthcoming project. The analysis has been carried out using MATLAB software for both proposed single circuit horizontal configuration and double circuit vertical configuration. Electric and Magnetic fields at power frequency are analyzed for various scenarios like varying height of ground clearance of conductors, fields at ground level, four meter and eight meter above ground level. Magnetic fields at different line loadings are analyzed for both the circuits. These results are compared with standard limits of exposure to human beings published by International Commission for Non-ionizing Radiation Protection (ICNIRP) and IEEE to examine the safety. Purpose of this study is to provide factual information on electrical and magnetic characteristics of 1200 KV AC power line and its biological effects on people, animals and plants.
