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”
