■要約(英語) This paper describes some experimental results of the semi-simultaneous observation of partial discharges (PD) signal, light emission of PD and visible images of PD source, and the detection of dissolved gasses in an oil gap on the oil impregnated paper insulation system. Firstly, an experimental system for observing PD signal, light emission and visible images semi-simultaneously was constructed. Using the system, it was confirmed that bubbles were generated at the place where the light emission was observed. In addition, it was found that the phase resolved PD pattern changed to patterns that PD occurred in voids as bubbles increased under the over-voltage application. Secondly, dissolved gasses in insulating oil in an oil gap were investigated by the dissolved gas analysis. As a result, it was revealed that dissolved gasses can be detected by the experimental system and dissolved gasses increased as the duration that PD occurred increased.
