Electromagnetic field evaluation in building located close to high-voltage overhead line

The magnetic and electric fields created of overhead line located in a densely populated area, near a residential building are investigated. The goal of this study is to model the fields created of 110 kV distribution line, located in highly urbanized environment and to evaluate the field impact on the residential building, situated very close after new construction. The electromagnetic compatibility of high-voltage line is considered. To find the electromagnetic field components, a method using numerical solution of Maxwell's equations by finite-element method FEM is used. The magnetic field model is based on Poisson's equation and on using of magnetic vector-potential. A modeling and simulation makes it possible to analyze real configuration and evaluate magnetic field levels and to establish electromagnetic compatibility. The electric and magnetic field levels in areas of the building are evaluate to verify the requirements of necessary exposure. The electromagnetic field has been investigated, taking into account the closer vicinity, where located a building recently built near the power line and it is possible to obtain high levels of the field. A magnetic flux density has relatively large values in a several areas of the building. The obtained electrical intensity levels are low, relative to the permissible norms for public exposure and ensure necessary safety requirements. The study allows the influence determination of the magnetic field and electric field of humans and can be evaluated risks of human health.
