Abstract
AbstractThe aim of this work is to study the relationship between the technical state of a power transformer and the parameters of the higher harmonic components of currents and voltages generated by it. An experimental setup was developed to study the parameters of the higher harmonic components of currents and voltages generated by a dry three-phase power transformer. The research results are given in the form of diagrams reflecting the change in the spectrum of harmonic components (from 3 to 13 inclusively) of phase currents and voltages when simulating various transformer damages. Regularities of changes in these parameters are revealed and the possibility of their use for assessing the technical condition and predicting the resource of power transformers is shown.KeywordsPower transformerHigher harmonic componentsVoltages
