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.

Harmonic Mitigation Using Phase-shifting Transformers and Harmonic Filters

Published by Alex Roderick, EE Power – Technical Articles: Harmonic Mitigation Using Phase-shifting Transformers and Harmonic Filters, May 21, 2021. Learn about how minimise the presence of harmonics in an electrical system with harmonic transformers and filters. Three-phase loads do not generate triplen harmonics. Therefore, harmonic problems in situations where 3-phase loads dominate are primarily fromContinue reading “Harmonic Mitigation Using Phase-shifting Transformers and Harmonic Filters”
