Application of Additional Grounded Wires in High Voltage Overhead Power Lines to Reduce the Intensity of Electric Field Generated by Phase Wires
Pubsliehd by Jacek GUMIELA1, Dariusz SZTAFROWSKI1 Politechnika Wrocławska, Katedra Energoelektryki (1) Abstract. To minimize interference with the environment it is important to make every effort already at the design stage to spare the trouble associated with additional investment later on. Due to the value of land in urban areas, it is beneficial to take necessaryContinue reading “Application of Additional Grounded Wires in High Voltage Overhead Power Lines to Reduce the Intensity of Electric Field Generated by Phase Wires”

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.
