Sažetak

This paper analyzes voltage sags distribution for distribution feeder in eastern Croatia. It presents the result of online power quality indices monitoring at 110/35 kV transformer station. Measurements were performed at the secondary sides of two transformers, by the power quality network analyzers. Results are aggregated and statistically arranged: voltage events were classified according to the EN 50160 and IEEE 1159:1995, and RMS variation performance indices were calculated. The research was performed during the Leonardo Power Quality Initiative project, since the Faculty of Electrical Engineering in Osijek was the LPQI's affiliate partner.
