要約(英語): The purpose of this study is to establish an online partial discharge (PD) diagnosis method in rotating machines using transient earth voltage (TEV) sensor and high frequency CT sensor which are relatively inexpensive and easy to install, as compared to aging state diagnosis by the conventional offline diagnosis. In this paper, on-line partial discharge measurements using several TEV sensors were performed and compared with signals detected by patch antenna and high-frequency current (CT) sensors, which are commonly used sensors. The results show that TEV sensor is relatively simple and useful for the on-line PD monitoring.
