The partial discharge (PD) testing is a promising method of stator winding insulation of hydrogenerator conditions monitoring. Therefore, the on-line PD testing has been used to provide useful information to diagnose and monitor the integrity of stator winding insulation of many hydrogenerators. In this paper, we have developed insulation diagnosis system of on-line hydrogenerator stator windings using acoustic emission (AE) sensors. Using this developed system, we estimated maximum PD position on stator windings that were the weakest point of insulation of hydrogenerator. Additionally, we investigated that this system was very useful for insulation diagnosis of hydrogenerator by comparing off-line test with AE measurement.}, pages = {215--220}, title = {AE法による水車発電機固定子巻線の絶縁診断システムの開発}, volume = {33}, year = {2004}, yomi = {タケムラ, アキト and ウエダ, タカシ and カネコ, タダミツ and タケノウチ, オサム and ソン, ヤルブン and オオツボ, マサヒサ and ホンダ, チカヒサ and フクラ, アツシ and タナベ, ヤスノリ and タナカ, カズヒロ and ウエダ, タカシ and カネコ, タダミツ and ソン, ヤルブン} }
