Abstract in another language
This paper deals with the question how realistic the voltage waveform in partial discharge (PD) tests has
to be to obtain realistic results for the PD inception voltage (PDIV) of inverter driven machines in offline PD
tests. Therefore, the influence of different parameters of pulsed voltage waveforms is investigated. The
PDIV measurement is done with a self-build test setup and PD sensor. Applying an asymmetrical voltage
stress with longer duration of one polarity significantly decreases the PDIV. Increasing the pulse times
also reduces the PDIV. The pause time between pulses with different polarity is found to be negligible in
common automotive applications. The dV/dt in combination with the resulting voltage overshoot is also
very important and has to be further investigated.
