Measurement and analysis of magnetic field radiation near 132KV power lines

Nowadays, due to the rapid development of the countries, the High voltage lines are become inside the cities. The magnetic radiation near high voltage transmission lines is very important issue that both the researchers and the population are worry about. Many previous work states that, it is dangerous not only to people but even to our fauna and flora. It causes cancer and some other illness such as Leukemia. Hence, investigating the magnetic field is tremendously important for the safety of the people. We had developed some equations and Maltlab Graphic User Interface for double circuit 132Kv vertical configuration base on Bio-savart´s law and Maxwell´s equations, to make easy for the researchers to calculate the magnetic field, It was applied the superposition method of multiple conductors. Moreover, the measurement was done by using Electric and Magnetic Field Digital Exposure System to collect data in Johor, Malaysia. Based on our results there are a good number of parameters that control the magnetic field; the current magnitude, the high of the conductor above the ground and the space between the conductors. The correct phase arrangement can reduces the magnetic up to 91.5% and the increment of 8m in the height will reduce 79% of magnetic emission.
