| 内容記述 | Considering the latest development of advanced information society, a stable power supply should be maintained. For transmission and distribution lines, cross-linked polyethylene (XLPE) cable plays an important role in distributing the stable electric power to customers. Electric failure for the XLPE cable decreases year by year because of progress of manufacturing. However, at joint and terminal sections of XLPE cables, partial discharges (PDs) occur in defects of insulating materials. Measurement of partial discharges (PDs) at joint and terminal sections in XLPE cables is useful for stable power supply because defects at joint and terminal sections occupy 30% of electric failures in Japan. The purpose of our study is establishment of an insulation deterioration diagnostic technique based on detection of PDs using acoustic emission (AE) sensors. We here evaluated temporal variation in AE signal and discharge current under a difference electric field. AE sensor was used for detecting AE signal reflecting elastic wave due to discharge. Frequency of a power source was 1kHz, which was about 16 times higher than that of a normal operating source and increased generation of PD per unit time. Based on the results, we showed that the incidence rate of AE signal and an etching rate increassed exponentially with increasing the electric field. | |||||||||||
