Analysis of magnetic field effects operators working a power transmission line using 3-D finite element method

The power transmission line is crucial to the energy system in the country. There is a strong emphasis on industry sectors. Engineers have a duty to protect and maintain power transmission lines systems. This research has brought the power transmission system of the Electricity Authority of Thailand to analyze the simulation results, proposes a set of mathematical models presenting magnetic fields caused by 115 kV power transmission line hung over a 22 kV for the operators working on the transmission 22 kV systems by using a set of second-order of PDE. The simulate conduct here in is based on the 3-D FEM in the time harmonic mode, MATLAB programming to show the effects of magnetic fields around power transmission lines and magnetic field distribution in staff to perform work. An investigate the magnetic fields acting on a human in comparative with ICNIRP standard.
