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 distribution of electricfeild strongly influenced tracking deterioration characteristics in electrode shape.}, pages = {149--154}, title = {ゴムシートを用いたトラッキング劣化試験におけるAE特性}, volume = {46}, year = {2016}, yomi = {ナカムラ, トモヤ and シラハマ, ユウゴ and ヒラシマ, トシキ and サコダ, タツヤ and シラハマ, ユウゴ and ヒラシマ, トシキ} }
