内容記述
Measurement of partial discharges (PDs) at joint and terminal sections in cross-linked polyethylene (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 intensity, characteristics of frequency spectra and phase of the AE signal for tracking deterioration. The results showed that the deterioration phenomenon owing to tracking had plural progress stages.
