Abstract

Insulation of electric machines is the most vulnerable area in the reliability of operation and use of electric machines. Existing methods of insulation diagnostics do not provide quality testing of winding insulation of windings. The existing normative method provides for exceeding the rated voltage by only 30%, which can detect only multi-closed groups, so the pulse process is provided as a DC break that feeds the winding during testing and then analysis of the transient process indicating the level of defect and diagnostic system module, which can provide a system of planned and preventive repairs.
