Environmental risk analysis of electromagnetic field levels in power lines for smart grid infrastructure

Abstract

Smart grids bring more electrical equipment into cities, so the fields around this equipment need to be checked. Electric field strength (E) and magnetic flux density (B) in an underground transformer room, under a 380 kV, 50 Hz transmission line and near low and medium voltage distribution lines measured and expressed each reading as an exposure ratio (ER), i.e. as a percentage of the corresponding ICNIRP public reference level. The largest values were found 1 m above ground below the center conductor of the 380 kV line, where E was 1.396 kV/m (ER 27.9%) and B was 4.191 µT (ER 4.2%). For the same line, a three phase Biot–Savart expression came within about 4% of the measured B, while an ANSYS Maxwell model gave values 7%–21% above the analytical estimate over the current cases studied. On the risk scale adopted here, most locations fell into Category I or II. The transmission corridor was placed in Category III because of its electric field, even though no reading exceeded an ICNIRP reference level. The comparison also shows that the dominant field component differs between sources: E under the 380 kV line, B next to the transformer.
