Study on Safety Consideration of ELF Magnetic Fields Emanating from Power Transmission Line for Electric Railways

전철용 성전선로에서 발생되는 극저주파 자기장의 안전성에 관한연구

This paper shows that the configuration of power transmission lines currently in place is suitable on the basis of calculated magnetic field strengths. The magnetic fields were computed for typical current distributions on power transmission lines for electric railways, which are characterized by severe load fluctuations and phase distortions. The result of the numerical analysis are compared with th ELF guidelines of magnetic fields from several case studies. The final conclusion reached in that effects of the magnetic fields near power transmission lines for electric railways are not significant enough to cause a biological safety concern.
