Measurements at Thermal Power Plants in focus
During this winter we have seen a rising interest in power quality measurements at Swedish thermal power stations. Our rental instruments have been in constant operation. We have, therefore, supplemented our fleet of instruments further to guarantee high availability. We know from experience that many users want to measure when they perceive problems that need immediate action. By collecting and
Enhanced Unbalance Measurements
“UnBalance Advanced” is an enhanced unbalance measurement for voltage and current optionally available in 2013 version of UP-2210 and Unilyzer 902. UBA is the ideal tool for fi nding unbalance sources and planning for mitigation measures. Values stored are negative, positive and zero sequence with maximum and average values. The corresponding phase angles for the average sequences are also measured.
