要約(日本語): We investigate partial discharge (PD) distribution pattern in three phase construction such as three-phase gas insulated switchgear （GIS）. Three phase construction introduces a new parameter compared to single-phase one, namely the electric field eccentricity. The investigation on simplified three-phase GIS model showed that PD distribution pattern in the term of phase width where PD pulses appear is influenced by the eccentricity. When the eccntricity equal one (i.e. circularly rotating electric field) PD pulses are estimated to appear in overall phase of applied voltage, since the maximum electric field equals the minimum one. This paper discusses the effect of the presence of particle in the region with circularly rotating electric field on PD distribution pattern.
