EN The influence of obnoxious load manifests in voltage variations. One of available measures of such variations are voltage fluctuations indices: amplitude and rate. Usually the obnoxious influence is accompanied by the increase of fluctuation's amplitude. Although there are diagnostic cases when such increase is not present and the obnoxious influence manifests in increased rate of fluctuations. The paper proposes an approach to estimate parameters of obnoxious load for such case. At first the overview of four voltage fluctuations measures is given. Then the results of the measurements of the three different measures recorded in LV power grid are presented. Finally the method of load's parameters estimation is presented.
