In this article, a simple 2D finite element model is proposed for computing the RMS electric field strength generated by overhead power lines. The model it is implemented in FEMM 4.2, a high quality, open source finite element software for solving low frequency electromagnetic problems, for the particular case of a 110 kV single-circuit overhead power line. The results obtained with this model there are analyzed and then compared to those obtained by analytical calculations, revealing a very good agreement. The proposed FEMM 4.2 model it is primarily intended to assess the compliance with the electric field exposure limits established by health regulations, but other applications are also possible.

In this study, a simple 2D finite element model is proposed for computing the RMS magnetic flux density generated by overhead high-voltage power lines. The model is implemented in ANSYS Maxwell 2D electromagnetic simulation software, for the particular case of a 110 kV double-circuit overhead power line. The results obtained with this model are then compared to those obtained by analytical computation software, revealing a very good agreement. The proposed 2D ANSYS Maxwell model is mainly intended to check the compliance with the magnetic field exposure limits established by safety regulations, but other applications are also possible.

Exposure to low frequency magnetic fields has been a subject of health concern and scientific debate over the past decades. This issue stimulated the interest towards the development of methods and software tools for computing magnetic fields generated by various power-frequency systems. Underground power cables are widely used in urban areas, but they have not been investigated as much as other sources. In this study, the low frequency magnetic fields generated by a typical 12/20 kV underground power line will be assessed by both analytical computation, using a software tool developed in LabVIEW, and numerical simulation, with a 2D electromagnetic modelling software. The obtained results will be comparatively analyzed and checked against relevant exposure limits.

The study investigates the distribution of the extremely low-frequency magnetic field around multiple highvoltage overhead power lines in parallel configuration. It is conducted using a computation approach based on the finite element method for an arrangement of five 110-kV doublecircuit lines located in a suburban area of the Iasi city, Romania. Results obtained by numerical simulation are then compared to appropriate regulations regarding human exposure to magnetic fields. The cumulative effect of the magnetic fields from multiple overhead power lines is also discussed.

In this paper, a DC digital gaussmeter for measuring magnetic fields up to $\pm 1000 G( \pm 100$ mT) is presented. It consists of two interchangeable transverse magnetic field probes based on Hall-effect sensor integrated circuits (ICs), a data acquisition module developed around a 8-bit PIC18F4550 microcontroller, a standard 2x16 character LCD display and a 5 V power supply module operating from 6 AA batteries. The instrument features USB connectivity and LabVIEW software for PC remote control. The gaussmeter is suitable for a full range of DC magnetic field measurements, and can be used for both research and teaching activities.
