<p class="Abstract">In this article, we present our study of the relevance of the relative position of the human torso with respect to the plane of the supporting pylons of various Overhead High-Voltage Power Lines from the perspective of currents induced by the generated magnetic fields. A homogenous model of the human body that considers the trunk as an elliptic cylinder has been developed in CST Studio software. Due to the necessary theoretical brevity, the results obtained by the simulation for the loop currents along the perimeters associated with the large (28 cm) and, respectively, the small (16 cm) axis of the elliptical cross-section of the trunk are presented and discussed. Simulations have been performed for five relative positions (0°, 30°, 45°, 60°, 90°) of the human trunk with respect to the plane of the transmission towers and for two types of symmetric, double three-phase networks (110 kV and 640 A, 220 kV and 960 A, respectively), with the normal supporting poles SN 110252. We present the solutions and the selected boundary conditions with the aim of using CST software in the domain of industrial frequency. The obtained results make it possible to formulate recommendations on the reduction of human exposure to magnetic fields.</p>

This paper consists of an experimental and analytical characterisation of the electromagnetic environment in the medium surrounding a circuit of two 220-Kv power lines running in parallel. The analysis presented is divided into two main parts. The first part concerns an experimental study of the behaviour of the electric and magnetic fields generated by the selected double-circuit at ground level (0 m). While the second part simulates and calculates the field profiles generated by both the lines at different levels above the ground, from 0 m to the level close to the line conductors at 20 m above the ground, using the electrostatic and magnetostatic modules of the COMSOL multi-physics software. The implications of the results are discussed and compared with the International Commission on Non-Ionizing Radiation Protection reference levels for occupational and non-occupational exposures. Keywords: High-voltage power lines, low-frequency electromagnetic fields, finite element method, electromagnetic compatibility, inductive and capacitive coupling, standards.
