    Abstract: Analysis was made to the abnormal oil chromatography of a 750 kV high-voltage shunt reactor. By analyzing the long time online monitoring and off-line detection of the oil chromatography, it was judged that the defect in the reactor was intermittent partial discharge. Multiple methods were taken to detect the partial discharge to correctly locate the defect. According to the intermittent characteristics, this paper analyzed the possible causes of the discharge. The defect type, location and reason of the mentioned reactor were verified by the hoist checking and the laboratory simulation.
    Key words: shunt reactor; chromatography; intermittent partial discharge; high frequency partial discharge detection; ultrahigh frequency
