Evaluation technology of the insulation systems for high voltage frequency conversion motor was introduced, including thermal evaluation, acceptance test for mainwall insulation systems, and qualification tests for mainwall insulation systems, turn insulation systems, and stress control systems. It analyzed the difficulties met in electrical evaluation of the insulation systems, such as the unknown machine terminal voltages waveshape arising from converter operation, no reference systems can be used in mainwall insulation systems qualification tests, no test equipments to simulate the actual running situation of insulation systems. Methods to solve these problems were also discussed for reference.
