Abstract :
Comparison study was carried out on the partial discharge (PD) behaviors in a void under AC voltages with square-wave and sine-wave. The transition of the PD magnitude with aging under square-wave showed the same tendency as that under sine-wave. Moreover, some distinctive characteristics of PDs under square-voltage (e.g. more than two pulses after the voltage rise time and their transition with aging) were observed and their mechanisms were discussed
