000000308 520__ $$aThe paper deals with localization of sources of harmonics in a power system. At the beginning, the reasons for undertaking investigations are outlined. Then, the theoretical background of the presented method is presented. The method uses examination of the so-called voltage rate to localize the dominant harmonic source. During this examination it is assumed that (i) the voltage and current at the point of common coupling are measured, (ii) at the first stage internal impedances of equivalent sources representing the customer and utility sides are known, (iii) at the second stage only approximate knowledge of the mentioned impedances is possessed. After the principle of the method is described, features of the method are analyzed. At the end, the attention is paid to the main advantages of the method.
