Abstract

Magnetic field is produced whenever current flow based on the Ampere's Law. The study of magnetic field distribution in the vicinity of high voltage transmission lines is very important due to its potential health effects. This is because of the low frequency magnetic field from high voltage transmission lines which today are very close to building in the cities, due to the rapid development. According to WHO no real prove that magnetic radiation from power transmission line is hazardous to the people however, still the researchers and the population are concerned about it. This project is to analyze and measure the magnetic field emission from various configurations of 132Kv high voltage transmission line.The measurement was done by using EMDEX II Electric and Magnetic Field Digital Exposure System,which is a hardware and software package designed to measure, record, and analyze power frequency magnetic fields. The result shows that it is very below the limit sets by ICNIRP. We had developed some equations and Maltlab Graphic User Interface for double circuit 132Kv vertical configuration based on Bio-Savart's law and Maxwell's equations, to make easy for the researchers to calculate the magnetic field, it was use the superposition method of multiple conductors. to collect data both for time and distance varying in Batu Pahat, Malaysia. Furthermore, the emission was high within 10:45 am to 11:15 am and from 1pm to 3:30pm, the highest recorded value was 12mG. Based on our results there are a few number of parameters that determine the magnetic field, namely the current magnitude, the high of the conductor above the ground and the space between the conductors. The correct phase arrangement can reduced the magnetic up to 91.5% and the increment of 8m in the height will reduce 79% of magnetic emission.
