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”
