Novel Method of Calculating the Coefficient of Asymmetry in the Negative Sequence

The objective of this research paper is to presents a new approach for calculating the coefficient of asymmetry in the negative sequence. Power supply failures caused by the coefficient of asymmetry in negative sequences is analyzed. In addition, due to the failure of power supplies the resulting economic damages in domestic and foreign practice are given. The analysis is based on the existing methods of calculating the coefficient of asymmetry of the negative sequence, and also the use of domestic devices for monitoring the quality of electricity of a separate power system is proposed. The results of measurements of distribution transformer of the Zangiata district are presented. The acquired results validate the proposed approach technique.
