What are Overcurrent Protection Devices?
Published by Alex Roderick, EE Power – Technical Articles: What are Overcurrent Protection Devices?, February 10, 2021. Learn about the basics of overcurrent, how it occurs, and ways to protect against and prevent it in power circuits. To have a properly operating circuit, current flow should be confined to a safe level. This safe level ofContinue reading “What are Overcurrent Protection Devices?”
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”
