Safety assessment of ultra-high voltage transmission power lines with AC-750 kV

In this work, we presented the dosimetry of the extremely low frequency (ELF) electromagnetic field generated by the three-wires, three-phase ultra-high-voltage (UHV) power lines with AC-750 kV. The induced magnetic flux density and electric fields in both realistic child and adult body models were obtained by impedance method and the results were compared with the ICNIRP guidelines. For adult, the obtained values of magnetic fields were well below the ICNIRP Reference Level. While the induced electric fields in central nervous system (CNS) exceeds the ICNIRP Basic Restriction. For child, both the induced magnetic and electric fields in tissues were well below the ICNIRP guidelines. It suggests a potential health risks may be posed to adult standing under the AC-750 kV UHV power lines.
