要約(日本語): To study the aging mechanism of insulation caused by impulse voltage, multiple impulses with positive and negative polarities which can produce PDs were applied to the three-layer polyester (PET) films with a void to accelerate insulation degradation. Partial discharge (PD) measurements at AC voltage were carried out after bipolar impulse applications. Based on AC PD characteristic including PD inception voltage (PDIV) and phase-resolved partial discharge (PRPD) patterns, the insulation degradation of the samples was discussed with the number of impulses in this paper.
