Modeling of electromagnetic environment of transmission lines for studying effect of ELF-EMF.
By combining two groups of three-phase power lines, a modeling that can induce power frequency electromagnetic fields has been presented. Charge simulation method and Biot-Savart law have respectively been adopted to compute the three-dimensional electric and magnetic fields in exposed environment of the modeling. Simulations indicate that the intensity of electric field can reach up to 5 kil-volt per meter (kV/m) at ground level, and the magnetic flux density can amount to 15 microtesla (microT). A comparison has been conducted between the environments that mice and human bodies are exposed to. The paper concluded that the modeling can be utilized in studying white mice simultaneous exposure to power frequency electric field and magnetic field emitted from transmission lines.
