Abstract :
The Inverter surge is a high-voltage phenomenon that is generated by the overlap returning wave by impedance mismatching to an inverter and load like cables and motors. The inverter has been available by advancement of control system of electrical instrument, such as the industrial motor. The increase of current changing rate with the advance of power semiconductor causes the surge voltage to rise, increasing the number of failure events. The 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 repetitive impulse voltage generator has been developed which is used in detecting PD in the inverter surge. 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.
