Tangent delta test report form
Download as DOC, PDF2 likes6,075 views
This test report summarizes insulation testing performed on a stator winding. It includes measurements of tan-delta to evaluate dielectric losses, insulation resistance over time to calculate polarization and time constants, ohmic resistance measurements of each winding phase, and environmental data like temperature and humidity recorded during testing. The report lists key details of the customer, machine, and test results but does not include any overall conclusions about the insulation condition passing or failing acceptance criteria.
