This paper is focused on the description of the measurement and diagnostics analysis of two dry distribution transformers 22 / 0.4 kV, 0.8 MVA with epoxy resin winding insulation using acoustic emission analysis. It is one of the basic diagnostic and monitoring functions for remote measurement and acoustic measurement using acoustic camera. The dry distribution transformers generate acoustic emissions, thanks to which we can analyze the operating and fault condition of the device. The article presents the use of an acoustic camera for operational monitoring and diagnostics through noise from the winding source and the ferromagnetic core of the transformer. The spatial distribution of the acoustic field as well as its spectra were analyzed. Preliminary results have shown that acoustic analysis can be a useful alternative for analyzing the design state of a power transformer.

The usage of surface acoustic waves (SAWs) is analyzed based on previous research in the investigation of behavior of liquid nanocomposites, such as doped liquid crystals and oil-based magnetic fluids namely under applied external magnetic field. The SAW propagation along the interface between fluid and substrate creates longitudinal wave the attenuation response of which can be measured and appears as a highly effective way to study processes induced by the external magnetic field. This is an advantage especially in the cases where the utilization of the longitudinal acoustic waves due to the higher viscosity of the investigated environment are not available. The interactions between the magnetic field and magnetic moments of nanoparticles in magnetic fluids give a rise to the aggregation of magnetic nanoparticles into chain or cluster formations that have a marked influence on the SAW attenuation. The measurement of the acoustic anisotropy is giving additional information about the structure of nanoparticles formation origination under an applied external field. In the case of liquid crystals doped with magnetic nanoparticles, the both threshold field and nematic-isotropic transition shift caused by the doping process with magnetic nanoparticles can be registered by SAW. The reason is in an orientational coupling between dipole moments of LC molecules and nanoparticles. The effect of particle concentration on the magnitude of structural changes invoked by the external field plays also an important role.

The article presents a comparison of the currently used solutions in the field of insulating oils with the new Nynas NYTRO BIO 300X bio-carbon oil. The paper shows the results of measurements of an electrotechnical pressboard sample impregnated with bio-carbon oil, the moisture content of which was 4% by weight. Measurements made using the FDS method in the frequency range from 10 mHz to 5 kHz at the temperatures of 293.15 K, 301.15 K, 309.15 K, 317.15 K, 325.15 K and 333.15 K, made it possible to determine the frequency-temperature dependences of the following electrical parameters: admittance, phase shift angle, loss tangent, conductivity and permittivity.

In the paper we deal with the issue of using cloud in academic environment, specifically in process of education at Department of information networks, University of Zilina (KIS UNIZA). The paper presents two views on the use of the cloud in the educational process. The first is the user’s view, when the services offered by the cloud are used, and the second is from the administrator’s point of view in our private cloud. Then we present how we applied these two views in the educational process at our department.

This study aims to investigate the effect of grid frequency on changes in the proliferative activity of eukaryotic Saccharomyces cerevisiae cells in vitro. As the extremely low-frequency electromagnetic field affects humanity, it is essential to examine its influence on living organisms. This particular area remains unclear, especially in long-term radiation. The grid frequency and magnetic flux density of the Earth's magnetic field were applied. This paper presents the irradiation including field parameters in the ratio of time-varying and static magnetic field at a certain level BAC / BDC = 1.8. In the light of recent results, there is now some concern about the compliance of grid frequency with conditions of ion parametric resonance. Using V. V. Lednev’s formula, 50 Hz frequency is close to the cyclotron motion of Mg2+ in the eucaryotic cell. Hence, the maximum stimulation effect of the field was achieved at the coil position E, with the number of cells in the exposed sample being 129 % more than in the control sample. On the other hand, the maximum inhibition was detected in the coil sample D with a yeast growth coefficient of -67 %. Presented data may have important implications for the long-term exposure of ELF-EMF which may shed some light on the issue.
本研究旨在探讨栅格频率对真核酿酒酵母细胞体外增殖活性变化的影响。由于极低频电磁场对人类的影响，研究其对生物的影响是必要的。这个特定的区域仍然不清楚，特别是在长期辐射中。采用地球磁场的栅格频率和磁通密度。本文给出了在一定水平下，含时变磁场与静磁场之比的场参数辐照BAC / BDC = 1.8。根据最近的结果，现在有一些关注网格频率与离子参数共振条件的遵从性。利用V. V. Lednev公式，50 Hz的频率接近真核细胞中Mg2+的回旋运动。因此，在线圈位置E处，电场的刺激效果最大，暴露样品中的细胞数量比对照样品多129%。另一方面，在线圈样品D中检测到最大的抑制作用，酵母生长系数为- 67%。所提供的数据可能对长期接触极低频电磁场有重要影响，这可能对这个问题有所启发。

This article focuses on the modelling and simulation of high-frequency electromagnetic field thermal effects on tumour tissue. It studies how a commonly used EMF frequency in hyperthermia influences the distribution of specific absorption rate (SAR) in a heterogeneous woman's breast model. We built a simulation model with two radiating antenna topologies, and we changed the location of the tumour in the breast to three different locations. The simulation results were compared and evaluated.

A typical problem related to the operation of DC railway traction systems are stray currents. Spreading through the ground in the vicinity of the railroad tracks, DC stray currents pose due to the electro-chemical corrosion effects a serious threat to all metallic structures in the ground that form a parallel path for the ground currents. However, the presence of stray currents is not strictly limited only to the direct vicinity of railways. Due to the presence of conductive elements like gas pipes, water pipes, grounding systems of electrical networks etc., stray currents can spread also to more distant areas, where the presence of stray currents is not expected. One of the possible elements contributing to the spreading of stray currents are also high voltage overhead power lines. This paper presents a possible technique for analyzing the influence of overhead powerlines on the spreading of stray currents in a given area.

The paper deals with the evaluation of the power loss generation of the 3-phase NPC converter. The efficiency performance of any power semiconductor system is currently main qualitative indicator due to several reasons. Therefore, the evaluation of the power losses is one of the initial stages of design of power converter to properly estimate requirements on thermal performance as well, thus optimized cooling system can be realized. Because currently there are various procedure how to estimate power dissipation, the focus here is given on the comparison of the results received from piece-wised linear simulator and from mathematical calculations recommended for analyzed converter topology. The main aim of this study is to evaluate the accuracy of piece-wised linearized simulators, whether simplification of the simulation analysis potentially reduces usability of the information relevant for efficiency estimation. From received analysis is seen, that accuracy of the simulation model presented here, provides sufficiently accurate results for further design issues.
