| description | The relevance of the research is related to the fact that at the present time geo asset exploration, extraction, transportation in oil, mining, coal, chemical and other industries are subjected to a high level of mechanization and automation involving electrical machines. The reliability and availability of these machines operation depend on condition of turn insulation (the enamel insulation of winding wires plays its role), therefore it is a critical issue to improve the control of enamel insulation of winding wires, increasing their quality and reliability. The aim of the research is to study the physical processes in a primary converter of defects in enamel insulation for justifying the selection of the mentioned converter design, evaluating and optimizing its metrological characteristics. Methods. The oscillographic method is used to study the characteristics of the discharge in the air ignited between the sensor and the wire at the place of a defect. The micrometers are applied to determine the defect geometry in the enamel insulation and the distance from the sensor to the border of the defective area. The high-voltage technique are used to study the characteristics of nature and type of the discharge in the gap between the sensor and the wire strand in defective areas of enamel insulation.
