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”

Harmonics in Electrical Power Systems and how to remove them by using filters in ETAP

Published by Zia Hameed1, Muhammad Rafay Khan Sial2, Adnan Yousaf3, Muhammad Usman Hashmi,Faculty of Engineering and Technology, Superior University, 17-km off Raiwind Road Lahore PakistanEmails: zia.hameed@superior.edu.pk, rafay.khan@superior.edu.pk, adnan.yousaf@superior.edu.pk Abstract—Power System Harmonics is a real point of concern for Electrical Engineers. In power systems, non-linear loads are permanently connected, unlike transients and other distortions are produced.Continue reading “Harmonics in Electrical Power Systems and how to remove them by using filters in ETAP”
