Abstract

This paper presents the results of power quality research in low voltage distribution network of the second biggest city in Serbia, Nis. The research is based on the measurements in transformers stations 10/0.4 kV that supply different load classes and that are located in different parts of the city. Power quality indices - total and individual harmonic distortions, unbalance factor and RMS voltage variation are analysed and compared with IEEE Standard 519 and EN 50160 limits. The results are grouped and discussed according to load classes that considered transformer stations supply.
