Experimental and Modeling of Electromagnetic Environment in the Vicinity of High Voltage Power Lines
Safety and Health at Work, 2015
Background: This 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 multilines high voltage power systems (MLHV) on the health of the workers and people living in proximity of substations has been analyzed. Methods: Experimental 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. Results: The 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. Conclusion: We 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.

Residential Area Medium Voltage Power Lines; Public Health, and Electric and Magnetic Field Levels
In this study, the electric and magnetic fields occurred around the medium voltage power distribution lines (MV-PDL) in the residential area have been analyzed, and different MV and LV power distribution lines (PDL) in Antalya were selected in order to investigate the electromagnetic field exposure according to yearly-based current load on power lines. Knowledge of magnetic field levels determined around power lines is so important for completing acceptable epidemiological studies, and medium voltage power lines established in the residential area close to the apartments have been investigated. There are houses and apartments in a distance of 10m or less which have potential for child leukemia, since magnetic field levels are around 0.4 µT and up.

In this paper we present a modeling and simulation, the methodology for calculating the electromagnetic field radiated by the high voltage (HV) lines and for selection of analytical models that interpret the electric and magnetic fields as a function of the distance to the target object. The results were compared with measurements carried out on site where the HV lines are present through a neighborhood of a large agglomeration in the city of Tebessa, for over 50 years. Following published standards establishing the human to HV power line distances for professional exposure or in the case of low frequency field exposure the results obtained by calculations /simulation and measurement in this work, enable us to recommend possible solutions for the electromagnetic pollution issues in the town of Tebessa and thus to reduce the permanent danger to the public considering also the legislative vacuum and the poor preoccupation of official authorities.
The increase in electricity consumption, population, and land use has now forced high voltage transmission lines (HVTLs) either to pass or be installed around or through urban cities. This increases the level of human exposure to electromagnetic field radiation as this field produced around the HVTLs extends outwards covering some distance. This may cause a number of health hazards. It is even dangerous to a human who touch any metallic object in proximity of the HVTL, as it may have an appreciable voltage induced on it due to inductive, capacitive or resistive interference from the line. This paper evaluates the magnetic field produced at mid-span by a 132kV, and a 330kV, 50Hz adjacent HVTLs with horizontal and vertical configuration in Akure, a city in South Western Nigeria using analytical method from electromagnetic field theory. This is then compared to the recommended standard limit of public exposure to magnetic field. The results of the computation showed that currently, the general public exposure to the magnetic field along the HVTLs is safe. However, right of way (ROW) along the power lines is being violated as buildings and work places exist within the ROW. Keywords-health hazard, high voltage transmission lines, limit of public exposure, magnetic flux density, right of way.

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.
The purpose of this study was to investigate potential health concerns linked to electromagnetic field (EMF) exposure from high-voltage power lines and develop a thorough knowledge of the underlying mechanisms causing these effects. The study looks into how Specific Absorption Rate (SAR) varies, how temperatures are distributed, and how these things affect people's health when they are close to electricity grid lines. The discretization finite difference approach was employed in this study to describe the electromagnetic waves, absorption rate, and temperature. The findings show that there is a considerable variation in SAR values, from 0.0000 to 0.0072 W/kg, and that as distance from the grid increases, SAR decreases from 1.0 to 0.0 W/kg. The study also shows that stronger electric fields cause temperatures to rise close to grid lines. These results highlight the significance of comprehending and reducing possible health concerns related to electromagnetic field exposure close to electricity infrastructure. To reduce exposure and safeguard public health, it is advised that regulatory rules, public awareness campaigns, and urban planning efforts be implemented in light of the observed variability of surface radiation and temperature swings. Effective solutions to safeguard the safety of people living and working near electrical grid lines must be implemented in concert with government agencies, utility companies, healthcare providers, and community groups. Stakeholders can create knowledgeable policies and practices to encourage safer living conditions and lessen the possible negative impacts of electromagnetic field exposure on human health by considering these findings.

Investigation of Field Induced Effect of High Voltage Transmission Line in Calabar South, Nigeria
2018
Due to increase in energy cost of transmission, high voltage transmission becomes the most economical for the transfer of large amounts of electrical power, because the higher the transmission voltage, the more efficient and cheaper the transmission. Due to increase in population, the towns are expanding, and naturally result in the construction of buildings near high voltage power lines. This research gives an in depth analysis of fields emitted by 11 kV and 33 kV power line and also describes in details the points where the highest field emission (at distance of 50 m, 1.17 µT is recorded for magnetic field around 11 kV power line and beneath the power line a field of 0.82V/m was recorded for electric field) and compares measurements of this fields with the international standard threshold values of 5V/m and 0.1 µT for the public. The magnetic field shows field/health effect as its exceeds the threshold value at some point while the electric field at all points is still below the limit as recommended by International Commission of Non-Ionizing Radiation Protection (ICNIRP).
