“…The authors have developed an automatic measurement system which allows us to measure electrical discharge properties such as repetitive partial discharge inception voltage (RPDIV) using a repetitive impulse voltage generator that can change the magnitude of voltage and pulse width. [7] In addition, the RPDIV automatic measuring system allows evaluation of PD characteristics of motorette sample which is one of the test object determined in IECITS 60034-18-41 [8][9] .…”

The Inverter surge is a high-voltage phenomenon that is generated by the overlap returning waves by impedance mismatching among an inverter, cable and motor.The inverter has been available by advancement of control system of electrical instrument, such as the industrial motor.Insulation performance evaluation technology by partial discharge (PD) measurement is important because the mechanism leading to breakdown by the inverter surge is a cause of PD. In this study, a design methodology for the impulse generator for partial discharge test is developed. In addition, we measure repetitive PD inception voltage (RPDIV) at phase to phase, phase to ground and turn to turn in a motorette sample using automatic RPDIV measuring system and developed repetitive impulse voltage generator.As a result, it is found that generated voltage and current waveform varies depending on the motorette structure. It is also found that RPDIV of the motorette differs with and a without a varnish treatment. The repetitive impulse voltage is applied to confirm the insulation dignity of inverter-fed motor insulation.

“…Thus, it is strongly required to develop a new type of repetitive voltage impulse generator. From the viewpoint, in this study, a repetitive impulse voltage generator has been developed which is used in detecting PD in the inverter surge [4]. We also develop an automatic repetitive PD inception voltage (RPDIV) and extinction voltage (RPDEV) measurement system for testing inverter-fed motor insulation.…”

In this study, a repetitive impulse voltage generator has been developed for detecting RPDIV (Repetitive Partial Discharge Inception Voltage) and RPDEV (RPD Extinction Voltage) of motorette test specimen designated in IEC60034-18-41-TS in the inverter surge. The fabrication of a generator is also described using a high-power semiconductor module and a variable amplitude DC power source. A design methodology for the impulse generator for partial discharge test is developed. The developed generator can generate a given number of voltage impulses with rise time of larger than 200 ns and arbitrary pulse width at less than10 kHz of repetitive frequency and variable rate of applied voltage rise. Automatic PD measuring system including the repetitive voltage impulse generator was also developed. The system allows automatic data acquisition of RPDIV and RPDEV defined according to IEC61934TS as well as conventionally defined PDIV and PDEV. We report the result that repetitive impulse voltage was applied to confirm the insulation dignity of inverter-fed motor insulation using the repetitive impulse voltage generator.
