Experimental Evaluation and Analysis of Electric Power Quality in Electric Networks Municipal-Households

The article discusses the analysis and evaluation of the results of measurements of indicators of the quality of electricity, such as frequency deviation and slow voltage change in the electrical network municipal-households with a voltage of 0.4 kV. The comparison of measurement results is carried out according to GOST 32144-2013 and the reasons for the deterioration of individual indicators are determined. In order to determine the correspondence of the values of the frequency deviation and the slow change in voltage to the requirements of GOST 32144-2013, the measurement results of these indicators were carried out for statistical processing.
