However, under the recent economically severe condition of social environment, there is a strong demand to use these equipments to a life limit by understanding about their performance. Furthermore, in order to raise the utilization rates of the production facilities, the diagnosis at an on-line condition is also desired. In order to meet the requests, it is required to understand as correctly as possible the performance of these equipments under the on-line condition. In order to build up the insulation deterioration diagnosis of the on-line hydrogenerator stator windings, we measured the AE signal and the leakage current of neutral point grounding line attended with partial discharge for two hydrogenerators using with the hybrid insulation deterioration diagnosis device. We put in the device at the two hydrogenerators, and we measured the AE signal and the leakage current of neutral point grounding line for a long term, respectively.}, pages = {163--168}, title = {音響・電気的測定法を用いた運転中水車発電機の長期部分放電特性}, volume = {37}, year = {2008}, yomi = {ヒラタニ, リュウイチ and マエダ, イクヤ and カネコ, タダミツ and ツジ, トシノリ 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 サコダ, タツヤ and フクモト, ススム and トクミツ, アキヒロ and カイ, トシヤス and アンドウ, ミトシ and ヒラタニ, リュウイチ and カネコ, タダミツ and フクモト, ススム and トクミツ, アキヒロ} }
