IEC standard for the design and qualification of the insulation system of inverter-fed motors controlled by power electronics refers to the measurement of partial discharge inception voltage (PDIV) or repetitive partial discharge inception voltage (RPDIV). This is, however, not a simple testing procedure when carried out under repetitive impulse voltage. Indeed, impulse voltages cause strong switch-on/off...
According to International Electrotechnical Commission technical specification, repetitive square wave voltage (RSWV) should be used to do partial discharge (PD) measurements on low-voltage random wound inverter-fed motors. The repetitive partial discharge inception voltage (RPDIV) is used to evaluate the insulation reliability. Therefore, knowing the influence of RSWV waveform parameters on PD statistical...
