Measuring PQ Issues in a Bus Depot Using Unipower HW and Software
Published by Unipower AB, Metallgatan 4C, 44132 Alingsås, Sweden. Email: info@unipower.se Introduction This case study explores how advanced power quality measurement technology facilitated the diagnosis of severe power quality disturbances in a bus depot. These disturbances, which neither the bus operator nor the bus manufacturer initially attributed to electrical quality issues, were ultimately traced toContinue reading “Measuring PQ Issues in a Bus Depot Using Unipower HW and Software”
Transient Detection using Peak Detectors
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”
