Abstract

Pulsating partial discharges (PD) occurring in point-dielectric gaps under an alternating voltage have been measured with a newly developed digital recording system. The dielectric is a cast epoxy resin with Al₂O₃ filler. In this paper, we analyze and report statistical characteristics of the PD including amplitude distribution, phase-of-occurrence distribution as well as the phase distributions of the individually selected PD pulses, e.g., the first-occurring or second-occurring pulse in each cycle
