Difference Between Grounding and Earthing
Published by Henry, theengineeringknowledge.com, May 20, 2020 The basic difference between grounding and earthing is that in grounding the conductor through which the current is flowing is connected with the ground while in earthing the conductor through which the current is not flowing is attached with the ground. In this post, we will have aContinue reading “Difference Between Grounding and Earthing”
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”

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”
Developing Infrastructure to Charge Electric Vehicles
Published by U.S. Department of Energy – Energy Efficiency and Renewable Energy Alternative Fuels Data Center Consumers and fleets considering electric vehicles (EVs)—which include all-electric vehicles and plug-in hybrid electric vehicles (PHEVs)—need access to charging stations. For most drivers, this starts with charging at home or at fleet facilities. Charging stations at workplaces and public destinations may help bolster market acceptanceContinue reading “Developing Infrastructure to Charge Electric Vehicles”
Insulation Failure Detection in EV Batteries
Published by Ryan Hsu, Bright Toward Industrial Co., Ltd., EE Power – Industry Article: Insulation Failure Detection in EV Batteries, May 15, 2023. One of the issues with electric vehicle batteries is insulation failure. A proven approach to detecting and correcting this failure lies in ground-fault detection. However, as higher voltages become increasingly common in electricContinue reading “Insulation Failure Detection in EV Batteries”
