Study of Factors Influencing Discharge Processes in Transformer Oil

The article provides a study of the influence of various factors on the insulation state of power transformers. When conducting research, the theory of experimental design was used. The numerical values of the factors that are most often encountered during the operation of power transformers are given. Experiment preparation and statistical data processing were carried out in the STATICTICA 6.0 software environment. The experiment was carried out using an automated acoustic diagnostic system and a simulator with a different set of defects. The obtained research results are used in the technique of recognizing acoustic signals from power transformers with varying degrees of development of insulation defects. The solution to the problem was carried out using regression analysis. The coefficients of the regression model are obtained and data on the adequacy of the mathematical model are presented. It is shown that the results of the research can be used to create reference signals for comparison with the signals of power transformers during operation.
