Kinsht N.V., Petrunko N.N. Discrete Diagnostic Model of Many High-Voltage Equipment Insulation Defects // Optoelectronics, Instrumentation and Data Processing. 2021,Том 57, Выпуск 2, Страницы 195 - 201. DOI 10.3103/S8756699021020084

We propose the problem of diagnosing insulation defects of high-voltage electrical equipment based on monitoring of partial discharges, which are the main diagnostic sign of the defects. However, partial discharges cannot be measured directly. The issues of constructing a diagnostic model of an insulation defect as a source of partial discharge series and the problem of differential diagnostics of individual defects based on the interpretation of the integral pattern of partial discharges as a set of single partial discharge times available for measurement are considered. Diagnostics is based on the idea of a mathematical problem of covering a set. An example is given.
