内容記述 | Electric failure for the Cross-linked Polyethylene (XLPE) cable decreases year by year because of progress of manufacturing. However, at joint and terminal sections of the XLPE cable, partial discharges (PDs) occur in defects of insulating materials. The PD generation can occur at any points in the insulation system where electric field strength exceeds a PD inception electric field and can develop until breakdown occurs. That is, PDs which are owing to local electrical stress in the insulation or on the surface of the insulation reflect a kind of sign of insulation deterioration. Therefore, PD measurement is a useful technique of assessing the insulation deterioration of XLPE cables. We propose a partial discharge locator (PDL) system which uses a time synchronization system instead of measuring PDs propagation velocity. The PDL is a two sides system in a distance of over 1 km and possible to detect the fault position owing to PDs on the power cable without power interruption. In this study, we investigated how PDs propagate in XLPE cables which have a branch. | |||||
