 note = {Since the aging of electric facilities have become an important issue in Japan, safety of such facilities in operation and ensuring high reliability are highly demanded. It is also necessary for each electric power company to reduce the cost for maintaining, managing, operating, and updating facilities because of the electric power liberalization. For these backgrounds, some sorts of sophisticated technologies for on-line monitoring systems and deterioration diagnosis technologies are needed rapidly in order to avoid any electric failures. Our esearch is to develop partial discharge locator (PDL) which is to locate cable faults by detecting current pulses generated by partial discharges (PDs). This paper presented theoretical analysis of frequency characteristics of a PD pulse on a branch line for PDL adaptability of multiple branch lines by using a simulation software. In addition, as a comparison to the simulation, we also carried out experiments using actual XLPE cables and confirmed the integrity verification of the simulation results. In this paper, we investigated PD characteristics caused by water trees in XLPE cables. It was found out that PDs can be generated by water trees. Therefore, PDL can be used for locating water tree.},
