摘要：
This paper investigates winding's aging of high voltage asynchronous motor. The paper is in a form of an experimental research manuscript. The long time experiments are performed on samples taken from new and used windings. Additional impregnated samples were also examined. The samples differ according to the technological process during the winding fabrication. During the experiment are determined: the breakdown voltage, the partial discharge threshold voltages and the curves of lifetime. Based on the obtained results, it was found how winding fabrication process affects insulation and insulation aging. It is suggested how it is possible to reduce the influence of the winding fabrication process on the inhomogeneity of its structure and the unevenness of its aging.
