Abstract

Among the phenomena significantly aggravating the quality of electric energy in the grid two are especially important: voltage fluctuations and deformations of voltage and current sinusoids.<br />The aim of the study described in the present paper was to improve the accuracy of signal converting in power measurements in non-linear receivers. The measurements of voltage and current were performed by means of a PC with measuring a card PCL-818L and with application software DasyLab 6.0 enabling the registration and converting of signals.
