要約(日本語): In general, three-phase equipment differs from single-phase equipment in two aspects: configuration and applied voltage. These difference results in different phenomena of electric field, partial discharge (PD), and PD induced electromagnetic wave (EMW). The special characteristics of electric field, PD, and EMW emitted by PD in three-phase gas insulated switchgear (GIS) model have been reported recently. The development of PD diagnostic device for three-phase equipment should consider these special characteristics. This research examines possibility of application of single phase PD monitoring device (PDM) in three-phase GIS model.Application of single-phase PDM device in three-phase GIS gave some erroneous in diagnosis results. The error is caused by error in phase recognition of PD pattern. The change in phase shift setting in PDM device based on the phase angle of applied voltage at maximum electric field on the particle tip gave better diagnostics.
