The evaluation of human exposure to electric and magnetic fields represents a subject of great scientific and public interest due to the biological effects of electromagnetic fields (EMFs) on the human body and the risks caused by them to living organisms. In this context, this article proposes a software program designed by the authors for the evaluation of human exposure to electric and magnetic fields at low frequencies (EMF software program), an application that can also be accessed from a mobile phone. The analytical model on which the EMF program is based is synthetically presented, and the application is then described. The first example implemented in the EMF program is taken from the existing literature on this subject, thus confirming the correctness and calculation precision of the program. Next, a case study is proposed for an overhead transmission line of 400 KV from the Cluj-Napoca area, Romania, for which the electric and magnetic fields are first measured experimentally and then using the EMF program. The validation of the EMF software program is performed by comparing the obtained results with those measured experimentally and with those obtained with a commercial software program.

“…There are many methods that have been developed to determine the electric field strength under the OHTL. Among them are the quasi-static method [6], the classic image method [7][8][9], the vector magnetic potential method [10], the impedance characteristic equation method [11], the CDM method [12], the Biot Savart method [1], the integral equations method [13], the surface integral equation method [14], the 3D integration method [15], the surface voltage gradient method [16] and the finite element method [13]. However, the currently available methods of calculating the electric field strength under the 150 KV OHTL do not accomodate the layered medium under the OHTL.…”

There have been many methods used to determine the electric field strength under the 150 KV overhead transmission lines (OHTL). Since it is simple and can be used for a homogeneous and multilayer medium, the method chosen for modeling the electric field under the OHTL is the complex image method (CIM). The results obtained show that the electric field strength obtained by the CIM is in agreement with that obtained by Complex Determine Method (CDM). Furthermore, the results obtained from the CIM model fit well with the field data. The OHTL height that must be raised so that the electric field strength under the OHTL will meet the WHO quality standards is 3 m at location A and 2 m at location B. These results show that modelling the electric field under the OHTL using CIM is exellent.

“…This accelerates the aging process of insulating paper, transformer oil, and magnetic system. Recently, there has been a growing interest in evaluating the influence of harmonics on power transformers, as evidenced by the papers of the international conferences [10][11][12][13][14][15][16] This paper provides an overview of the characteristics used in publications to evaluate the influence of harmonics on transformers. The results of their calculations are presented.…”

The electrical equipment operation is cost-effective and reliable when operating parameters of the electrical network correspond to the rated data of the equipment. The real operation conditions, however, differ from those required for electrical equipment, which negatively affects its efficiency. The non-sinusoidal conditions in electrical networks are currently very common. The paper provides an overview of the characteristics obtained from an analysis of publications, which are used to evaluate the effect of the non-sinusoidal conditions on power transformers. The results of the calculation of these characteristics for a transformer installed at a railway traction substation are presented. Parameters of the non-sinusoidal conditions are obtained as a result of measurements.
