The insulation structure and process of stator winding of nuclear power generator for 1750 MW are complex, not only present new challenges to the insulation technology of stator winding, also put forward higher requirements of insulation test technology of stator winding. This paper mainly introduces the test principles, test methods and analysis of test results of dielectric dissipation factor, partial discharge and DC leakage current of stator winding. The test results meet the requirements of relevant standards and also provide a strong guarantee for the safe and reliable operation of the nuclear unit.
