The expected technological development, mostly found in the communication domain, will accordingly increase the number of artificial electromagnetic field (EMF) sources, as well as corresponding EMF exposure in the environment. Thus, EMF monitoring has been required worldwide and some innovative monitoring systems are being developed. Some of them are intended to simultaneously perform long-term monitoring...
Exposure to low-frequency electromagnetic fields (EMF) has become an issue considering a number of high-power low-frequency EMF sources installed in residential environment. Therefore, the EMF monitoring and appropriate exposure assessment are highly important regarding the safety, since residents can spend considerable time in the vicinity of such high-power objects. This short paper brings the case...
The inductive assemblies with variable geometry have recently been proposed for potential electromagnetic (EM) energy harvesting utilization. Such inductors are capable of changing their initial geometry under the influence of some external force, collecting additional magnetic flux and producing increased induced voltage. In order to evaluate performance of such inductors, regarding increase of its...
The energy harvesting applications becomes omnipresent, utilizing different harvesting techniques to collect energy from ambient. Recently, the electromagnetic field energy harvesting attracted attention, with objective to provide nearly unlimited power supply, particularly for variety of the low-power electronic devices. Furthermore, the inductive assemblies have been recognized as reliable, low...
Determination of normal magnetization curve is a well known problem, solved and described in many papers. But none of the normal magnetization curve measurements were performed applying current transformer instead of voltage toroidal transformer sample. Comparing the application of current transformer versus the application of voltage transformer, several different procedures and approaches appeared...
Recently, the concept of energy harvesting has started to be considered and utilized in a variety of applications. The energy of the ambient has been exploited, employing different harvesting techniques, in order to provide the inexhaustible supply for the range of electronic devices. Concerning the energy stored in the electromagnetic field, among the known and prominent harvesting approaches, the...
The most known sources of the low-frequency electromagnetic field (EMF) can be found in electric power systems. Those systems and their power distribution parts have become the backbone of economic, technological and overall development of human society, intensely in modern-days. The actual humanity highly depends on the reliable power supply and thus a number of power distribution substations have...
The intensive increase of the number of population in modern cities demands a highly reliable power supply, requiring power distribution systems that will accomplish this challenging task. In order to increase the reliability of consumers supply, the additional power distribution substations are commonly installed, which in time become surrounded by the expanded residential areas. In consequence,...
The Serbian electromagnetic field (EMF) monitoring network - SEMONT is a network of remote wireless sensor nodes that continuously measure EMF level in the environment, in order to assess the non-ionizing radiation exposure of the general population and perform a real-time dissemination of the assessment results to the public. This paper presents some details of implementation and results of the SEMONT...
Aluminum Conductor Steel Reinforced (ACSR) steel core is made of a nonlinear ferromagnetic material and usually, its permeability values are not known. Hence those values must be determined by measurements. For such measurements, two samples of torus transformer were constructed. Applying well known methods, for different primary currents and different frequencies, numerous hysteresis loops were measured...
The Serbian Electromagnetic Field Monitoring Network — SEMONT is based on autonomous, remote sensor nodes, capable to monitor in-situ electromagnetic field in the environment and to wirelessly communicate with the central control station, uploading/downloading data. The SEMONT information network is intended for continuous monitoring of the low and high frequency field sources, performing the assessment...
