Modelling and evaluation of electromagnetic field of urban high-voltage power line

An electromagnetic field EMF generated by high voltage overhead transmission line in an urban environment is presented. The electromagnetic interference generated by overhead high-voltage HV line is considered. The levels of the electric field and magnetic field around HV urban lines are investigated. They are calculated analytically and simulated numerically for various realistic cases like normal mode and short circuit mode. The magnetic field of a high-voltage power line under lightning strike is also simulated. An impact of electromagnetic field in electrical devices in adjacent building and people, which is located nearby urban HV line, is being studied. Model validation of numerical simulation with measuring results of electric field of an existing transmission line 110 kV is done. Results of the electric and magnetic field analysis of the overhead urban line were assessed to check the compliance exposure limits with the existing requirements. The presented method for the electromagnetic field modeling could be used for the evaluation of the impact on the human body by simulations of different, unusual situations like lightning strike.
