The Influence of PQ-Monitor Connection on Voltage Dip Measurements
Paper i proceeding, 2004

This work addresses the influence of PQ monitor connection on the estimation of site and system voltage dip indices. It also presents the relation between sag magnitudes for phase-to-neutral and phase-to-phase monitoring. Stochastic assessment of voltage dips is used to generate fault caused events from which indices for both phase-to-neutral and phase-to-phase voltage sags are calculated. Results for one-year power quality monitoring program in a sensitive manufacturing process are also presented. Results considering the two monitor connections are analyzed.
