Development of Electromagnetic Environment of Three Phase Power Lines for Bio-Effects Evaluation

In order to evaluate the possible effects of electromagnetic irradiation of power lines on white mice, an electromagnetic environment was constructed in laboratory setting. Charge simulation method (CSM) and Biot-Savart law have respectively been adopted to compute the three-dimensional electric field and magnetic field of the environment. Both methods are programmed using the MATLAB software. Simulation and measurement indicate that the intensity of electric field can reach up to 10kil-volt per meter (kV/m) at ground level, and the magnetic flux density can reach as high as 100microtesla (μT). It is demonstrated that the electromagnetic environment can be utilized in studying white mice simultaneous exposure to extremely low frequency electric field and magnetic field emitted from power lines.
