변전소 건설로 인한 자기장 노출범위설정에 관한 연구

Abstract

The health risks from the magnetic fields exposure have been brought out difficulties in theconstruction of transformer substation. According to several epidemiologic studies and therelevant international organizations, magnetic fields should not exceed the exposure limits of3mG for the people living near electric power lines. The rigid regulation of the exposure levelsfor the elementary school and residental areas has been established already in Switzerland andItaly. Since 1998, the environmental impact assessment system in Korea has been reviewed forpower-frequency magnetic field by precautionary policies.In this study, the possible application of Prior Environmental Performance Review Systemfor the transformer substation was reviewed from the points of the properties of the power-frequency magnetic fields. The ranges and survey methods of the assessment for thetransformer substation were proposed. The ranges of magnetic fields was between 300m to500m for the 345kV transformer substation. It is necessary to develop further specificassessment methods for various high-voltage transformer substations.
