Measurement and Numerical Simulation of the Low-Frequency Electric Field Generated by an Overhead Power Line

In this study, the low-frequency electric field generated by a 110-kV double-circuit overhead power line is comparatively assessed by measurements and numerical simulations. Measurements were performed with a selfdeveloped 5 Hz – 2 kHz electric field sensor (EFS-01) in conjunction with a portable signal analyzing device, i.e. Fluke 43 single-phase power quality analyzer, while simulations were performed using a 2D finite element model developed in ANSYS Maxwell 2D. The results obtained by the two methods are in good agreement and in line with expected exposure field levels for such types of 110-kV overhead power lines.
