Fault Analysis and Diagnosis of High Voltage Side Bushing of 500kV Transformer
This paper analyzed and diagnosed a fault of 500kV high voltage bushing, and found insulation damage in phase A of the bushing by insulating oil chromatography test and high voltage test. The fault type of the bushing was analyzed and judged by characteristic gas method. According to the inspection results of bushing disintegration, the accuracy of analysis and judgment results is verified.
