Published by Jonny Carlsson, Unipower AB, http://www.unipower.se Background The main problem with transients in the electrical network is that a high voltage potential might break the isolation barrier in for example cables or other equipment in the electrical network. It may also harm semiconductors that are sensitive of high voltage. A transient voltage is byContinue reading “Transient Detection using Peak Detectors”

Dynamic Voltage Restorer for Voltage Unbalance Mitigation and Voltage Profile Improvement in Distribution Network
Publishd by Ahmed A. Abdullah AL-KARAKCHI1, Enaam ALBANNA2, Alya H. AL-RIFAIE3, Northern Technical University (1,2,3) ORCID: 1. 0000-0003-1151-3015; 2. 0000-0002-3974-0116; 3. 0000-0002-7978-2193 Abstract. Unbalanced network voltage damages utility and end-user equipment. Electrified trains, single-phase distributed generators, and line-toline connected industrial loads can increase voltage imbalances. Using Dynamic Voltage Restorer (DVR) at appropriate places is oneContinue reading “Dynamic Voltage Restorer for Voltage Unbalance Mitigation and Voltage Profile Improvement in Distribution Network”
An Overview of Harmonics in Electrical Systems
Published by Wesco | Anixter, Wesco International. What are harmonics? In an electric power system, a harmonic is a voltage or current at a multiple of the fundamental frequency of the system. Harmonics can best be described as the shape or characteristics of a voltage or current waveform relative to its fundamental frequency. When waveforms deviate from a sinewaveContinue reading “An Overview of Harmonics in Electrical Systems”
