The partial discharge(PD) is widely regarded as an important index for insulation state monitoring at home and abroad, however,assessment for insulation conditions of oil-paper in power transformers based on PD has no wide practical application. Therefore,we summarized the research status of insulation condition assessment of oil-paper in power transformers based on PD, and proposed its directions which need to be studied in depth and its growing trend, providing the basis for subsequent research. By analyz...
