Abstract:
This thesis presents the study and analysis of the effects of electric and magnetic fields on the residents in the high-voltage transmission zones with a computer simulation program and measurements. The electric and magnetic fields were investigated to find safety distance of the residents on the voltage of 24 and 69 kV for this study.
The comparison analysis of the electric and magnetic fields between the computer simulation program and the measurements was implemented according to the parameters in Rama 2 Road, Bangkok. All required parameters were measured and stored in the computer for the analysis.
The study results indicated that the maximum values of electric and magnetic fields were on the conductor and decreased when the distance was increased. The measurement results of the electric and magnetic fields of the voltage of 24 and 69 kV were also related in the same direction with the computer simulation results. It indicated that at the distance of 1.80 m was the safe distance from the electric and magnetic fields of the high voltage electrical tower according to the World Health Organization standard, which the electric field must not exceed 5,000 kV/m, and the magnetic field must not exceed 1,000 mG.
