Measurement and Modeling of Personal Exposure to the Electric and Magnetic Fields in the Vicinity of High Voltage Power Lines

Abstract

BackgroundThis work presents an experimental and modeling study of the electromagnetic environment in the vicinity of a high voltage substation located in eastern Algeria (Annaba city) specified with a very high population density. The effects of electromagnetic fields emanating from the coupled multi-lines high voltage power systems (MLHV) on the health of the workers and people living in proximity of substations has been analyzed.MethodsExperimental Measurements for the Multi-lines power system proposed have been conducted in the free space under the high voltage lines. Field's intensities were measured using a referenced and calibrated electromagnetic field meter PMM8053B for the levels 0 m, 1 m, 1.5 m and 1.8 m witch present the sensitive's parts as organs and major functions (head, heart, pelvis and feet) of the human body.ResultsThe measurement results were validated by numerical simulation using the finite element method and these results are compared with the limit values of the international standards.ConclusionWe project to set own national standards for exposure to electromagnetic fields, in order to achieve a regional database that will be at the disposal of partners concerned to ensure safety of people and mainly workers inside high voltage electrical substations.

Simulation of the Electromagnetic Field in the Vicinity of the Overhead Power Transmission Line

“…The interface of Magnetic Fields in the software uses equation (5) to determine the value of magnetic vector potential A, and consequently, the values of all fields derived from it (the magnetic field H and the magnetic flux density B). The electric current of the three phases is as follows [11][12]14]:…”

“…The development and extension of very high voltage electrical networks (VHV) generate and multiply the interactions and electromagnetic problems [1][2] which have a negative effect on environmental risk and human health, moreover they could expose the peoples working around them to serious diseases [3][4][5].…”

“…There are several experimental and simulation studies on electromagnetic characteristics near the power line [5][6]. The most of works is based on the evaluation of the product field around and near the power lines and comparing it with international norms [2][3][4], other studies have been carried out on the influence of the intensity of the electromagnetic field on the health and the environment [3][4], there are even studies on the reduction of the intensity of the field under the electric lines thanks to technical solutions [7][8].…”

Exposure of Live-Line Workers to Magnetic Fields: A Dosimetric Analysis

“…The exposure to electromagnetic fields produced by high-voltage facilities was considered in several published papers [5][6][7][8][9][10][11][12], focusing the attention to the electric and magnetic field strength, either by on-site measurements or by simulations. Different transmission lines configurations or exposure scenarios in substation were analyzed.…”

“…Likewise, a similar effect is suspected to happen for those who are living near or under high voltage electrical stations [ 40 ], where the electromagnetic waves may create such disturbances to the organisms [ 41 ] that could lead eventually to severe pathologies [ 42 , 43 ], especially if the organisms are sensitive to such influences.…”
