Published by Unipower AB, Metallgatan 4C, 44132 Alingsås, Sweden. Email: info@unipower.se We have received questions about disturbances in the grid. Do we have any examples? Here is an interesting example showing how disturbances spread through the network. A major frequency disturbance occured in Scandinavia on December 1, 2005. In this comparison we have compared measuring dataContinue reading “Upstream Frequency Disturbance”
