ABSTRACT: Recent decades have seen rapid advances in the field of electrical
engineering, such that our environment has become a sea of electrical and
magnetic signals, raising questions about the possible effects of low-frequency
electromagnetic fields on the environment and which are capable of modifying
and destroying our ecosystem. Particular interest was given in this article due
to a massive influx of population living near high voltage lines. The
analysis and simulation of the influence of low frequency electromagnetic
fields on living beings in the vicinity of high voltage sources 132 kV and 220
kV in urban areas in DR Congo is the subject of our research with a view to
estimating the level of exposure of humans to low frequency electromagnetic
fields. To carry out our research, we used the classic method of analyzing the
field produced near a high voltage line based on Maxwell’s image theory, the
Maxwell-Gauss theorem and Maxwell-Ampère theorem to model and quantify
low-frequency electromagnetic fields in the vicinity of high-voltage lines. The
2D FDTD numerical formulation was developed from telegraphers’ equations and
allowed us to obtain models of current and voltage induced by electromagnetic
fields on living beings below and near HV lines. The
different simulations carried out on the proposed models illustrate the effects
of the electrical and geometric parameters of the pylons on the distribution of
the electromagnetic field in the vicinity of the HV lines. The
results obtained were compared to the safety limits recommended by the
standards.
