Abstract

Magnetic field and electric field in extremely low frequency (ELF) condition on tower transmission line was expected to cause a biological effect to human health such as change in cells and hormone levels which it can be dangerous to health. However, there is no significant study to prove such illness that due to magnetic fields. Furthermore, there are many questions that need to be answered about magnetic field whether can harm human health. Moreover, it is needed to determine the limits of magnetic field exposures for the long term. The aim of this study is to analyse and compute the magnetic field strength at certain points for 132kV overhead transmission line in UTeM. Our aim is to determine the minimum requirement and safety distance right of ways (ROW) and safe area for public people near to overhead line based on magnetic field strength. To conduct this measurement, the magnetic field has measured by using the HI-3604 extreme low frequency (ELF) meter survey. The result from measurement was utilized for statistical analyses to ensure the significant result for the particular distance under the transmission line tower. The result from this project shows the public will get a minimum exposure of magnetic field at 24m from the conductors. So, the minimum safety distance of right of ways (ROW) is 24m. The exposure of the magnetic field by this 132kV transmission line shows it is within the standard and cannot harm or give effect to human health. So, this project gives a better understanding of the magnetic field exposures on the transmission line. In the future, this investigation can be done at the 275kV and 500kV overhead transmission line in Malaysia
