We studied usefulness of a frequency accelerated aging test by paying attention to the number of partial discharge (PD) pulses and the accumulated PD charges per a cycle of frequency of applied voltage. The results shows that a frequency accelerated aging test is useful when the accumulated PD charges per a cycle of frequency of applied voltage with higher than PD inception voltage are the almost same as that at a commercial frequency of 60 Hz. If applied frequency is 1 kHz, an accelerated aging test with 16.6 times faster than that for 60 Hz can be achieved.
