How to Reduce the Soil’s Resistivity
Published by Lorenzo Mari, EE Power – Technical Articles: How to Reduce the Soil’s Resistivity, September 28, 2020. Lowering the resistance of a grounding electrode is not always enough to reduce the soil’s resistivity. Reducing the resistivity of the soil around the electrodes can help achieve adequate resistance to the ground. The elements that most affectContinue reading “How to Reduce the Soil’s Resistivity”
Electromagnetic Disturbances Propagation Along a Grounding Grid Subjected to Lightning Currents
Published by Rafael ALIPIO, Renan SEGANTINI, Federal Centre of Technological Education of Minas Gerais Abstract. This paper assesses the transient distribution of potentials along a grounding grid subjected to currents representative of first and subsequent strokes. It is shown that the transient non-uniform distribution of potential along the grounding system may lead to the flowContinue reading “Electromagnetic Disturbances Propagation Along a Grounding Grid Subjected to Lightning Currents”
Influence of Distributed Generation on Sectionalizing Switches Placement in MV Distribution Networks
Published by Wojciech BĄCHOREK1, Mariusz BENESZ1, AGH University of Science and Technology (1) Abstract. This paper presents the influence of distributed generation DG and reclosers placement on the reliability of distribution network. The brute force method and evolutionary algorithm were used to solve the optimization task.

Methods for Determining Power Losses in Cable Lines with Non-Linear Load
Published by Łukasz TOPOLSKI, Jurij WARECKI, Zbigniew HANZELKA, AGH University of Science and Technology Abstract. Harmonic currents in power cables cause additional power losses associated with phenomena that increase the temperature of the cable insulation and make its service life shorter. For these reasons, it is important to choose methods for determining active power losses,Continue reading “Methods for Determining Power Losses in Cable Lines with Non-Linear Load”
