To ensure insulation system reliability of rotating machines driven by power electronics, accelerated tests under repetitive impulsive voltages should be performed on turn-to-turn insulation according to the standards provided by the International Electrotechnical Commission. The parameters of repetitive impulsive voltage can significantly influence insulation lifetime, and thus, voltage parameters...
Repetitive wave voltages should be used to perform partial discharge inception voltage (PDIV) tests on insulation systems of type I rotating machines fed by power electronics in qualification and type tests according to new standards published by International Electrotechnical Commission (IEC). To obtain objective test results, the influence of waveform parameters on PDIV results should be carefully...
Endurance tests under repetitive impulse voltages should be performed on inverter-fed motor insulation to evaluate its insulation performance according to the technical specification (TS) released by the International Electrical Commission (IEC), i.e. IEC TS 60034-18-42. To simplify testing procedures in the application, the TS allows life tests to be performed under sinusoidal waveform, as it assumes...
