“…The results calculated in this paper via FEM are compared to the results obtained by other either theoretical or experimental methods and listed in Table 1. The FEM results are shown to be in a satisfactory agreement with those achieved by Poljak et al [10] using the Boundary Element Method (BEM) and with experimental results of Chiba et al [8]. …”

“…However, in majority of real scenarios there exists an ohmic contact between the feet and the soil, particularly due to the influence of the soles of shoes. This contact is generally represented by an equivalent capacitor, e.g., [8,11,15]. In the model proposed in this work the soles are modeled by a volume of height d = 1.6 cm (height of the sole) and radius r = 11 cm, as indicated in Figure 6, characterized by a relative permittivity ε r = 3.…”

“…Note, that according to ICNIRP guidelines from 1998 [2] the current density was a main parameter for the estimation of extremely low frequency exposure effects, while the new ICNIRP guidelines from 2010 [3] propose the induced electric field instead of the induced current. However, there is a substantial amount of results for the current density in the relevant literature for the comparison purposes, e.g., [4][5][6][7][8][9][10][11][12][13]. Several methods have been used to calculate the current density induced in the human body due to exposure to low frequency fields, such as the Finite Difference Time Domain (FDTD) [4,5] the Finite Element Method (FEM) [6][7][8]; the Boundary Element Method (BEM) [9][10]; the impedance method [11] or the Transmission Line (TL) model [12].…”

Abstract-The paper presents an assessment of human exposure to extremely-low-frequency (ELF) electric field generated by a power line using the rotationally-cylindrical body model. The formulation is based on the Laplace type continuity equation. The induced current density in the three-dimensional (3D) model human body is obtained by solving the Laplace equation via the Finite element method (FEM). The main objective is to highlight some parameters influencing the distribution of the induced current density, such as the ohmic contact between the feet and the soil due to the soles of the shoes, and the electrical parameters of the soil. Furthermore, the influence of internal organs (the human model) to the induced current density distribution. The human body is represented by a homogeneous model and also by an inhomogeneous model composed of several organs namely brain, heart, lungs, liver and intestines, whose shapes were spheroid. The proposed model has been validated through comparison to either the experimental results or the theoretical results available in literature being computed by the aid of a homogeneous body model.

This paper evaluates the currents induced in the human body when exposed to extremely low frequency (60 Hz) electric fields by numerical modelling with boundary elements. The exposure is driven by the voltage of a rectangular panel representing the control keyboard of a power substation room. The main focus is to study the variations of the current density in the human body when located at different distances from the panel. In addition, the sensitivity of the results for the current density when considering the human body with and without its internal organs is estimated. The numerical approach is based on the three dimensional boundary element method (BEM) with the kernel of Laplace equation, in which the human body model considered is a simplified representation which allows parametric modifications of its geometry and physical properties.

This paper deals with human exposure to extremely low frequency (ELF) electric fields generated by a transformer substation. The problem is twofold, i.e. it implies the assessment of the power substation electric field and the related current density induced inside the human body. The ELF electric field generated from a power substation is determined by solving the Scalar Potential Integral Equation (SPIE) using the Source Element Method (SEM), a variant of the Indirect Boundary Element Method (IBEM). Knowing the electric field in the vicinity of a substation the current density induced inside a simplified cylindrical model of the human body is obtained by solving the Pocklington integrodifferential equation using the Galerkin-Bubnov Indirect Boundary Element Method (GB-IBEM).
