The partial discharge (PD) testing is a promising method of stator winding insulation of hydrogenerator conditions monitoring. Therefore, the on-Iine PD testing has been used to provide useful information to diagnose and monitor the integrity of stator winding insulation of many hydrogenerators. In the paper, we described the examination of PD characteristics of on-line two hydrogenerator stator windings by using acoustic emission detection technique, and we considered the influence of the operation environments such as coil temperature, humidity and stopping time.}, pages = {83--88}, title = {AE法を用いた水車発電機の運転環境条件による部分放電特性}, volume = {35}, year = {2006}, yomi = {ウエダ, タカシ and フジイ, タイシ and カネコ, タダミツ and タケノウチ, オサム and オオツボ, マサヒサ and ホンダ, チカヒサ and ツルタ, ヨシオ and イワモト, ヒデキ and トクミツ, アキヒロ and ウエダ, タカシ and カネコ, タダミツ and トクミツ, アキヒロ} }
