3D Electric Field Simulation and Proper Shielding Consideration Under Overhead High Voltage Transmission Lines in the Presence of Human Body

Electric field simulations and measurements under overhead high voltage transmission lines, in the presence of human body, are undertaken in this paper, in an effort to assess improvements in the finite element analysis (FEA) precision achieved by using 3-dimensional representation with respect to 2-dimensional one, enabling appropriate shielding consideration. The current work illustrates a more realistic representation of the electric field inside and in the vicinity of human bodies, close to the measurement’s sites, that is in qualitative agreement with previously proposed 2-D simulation techniques. However, field measurements and additional modeling clearly illustrate that such accumulation of electric fields is split among a plurality of conductive materials and human bodies when they are close to the vicinity of measurements and the power transmission lines. These field measurements enabled proper simulation and shielding design against electric field, permitting minimization of electric field under certain conditions, thus allowing for long time human activity or work, following certain precautions, in otherwise restricted areas in the vicinity of overhead transmission lines. This technology can be implemented in aluminum facades, doors, windows, and shaders, by means of using the metal as grounding means.
