Determination of the technical state of the stator of electric machines on the basis of measuring the characteristics of partial discharges
Abstract
The article deals with sources and reasons of partial discharges in the stator coil insulation. A data base is created containing typical standards and quantitative parameters of partial discharge specters in electrical machine coils taking into consideration test voltages, ageing time and positions of coil defects.
