MATHEMATICAL SUBSTANTIATION OF THE INFLUENCE OF DIAGNOSTIC SIGNS ON THE TECHNICAL CONDITION OF THE INTERPHASE INSULATION OF ELECTRIC MOTORS
In this scientific work, a study of the negative impact of diagnostic signs on the technical condition of the interphase insulation of electric motors was performed. A computer model was developed to determine the relationship between the leakage current through the interphase insulation and the phase currents. A computational experiment was conducted, where it was established that the damage to the interphase insula-tion reliably correlates with the differences between the phase currents, but not with the currents themselves. The obtained values of the correlation coefficient showed that there is a functional relationship between the insulation resistance and the difference in the phase currents of the electric motors, thus confirming the hy-pothesis of the influence of certain factors on the technical condition of the interphase insulation. It was de-termined that the probability of such damage occurring in the presence of a difference in phase currents in electric motors due to relevant factors is 33%. The obtained research results can be used in the development of models of diagnostic systems under the condition of monitoring the condition and prevention of insula-tion damage and prevention of emergency situations associated with its violations.
