Abstract
This paper presents the results of power quality measurements in distribution systems of commercial and office customers. The data collected show serious currents distortions, caused by the increase count of nonlinear loads. In many cases the levels of distortion are higher than defined limits in international power quality standards.The negative impact of harmonic distortions is discussed
