Abstract
A 220 k V potential transformer inner partial discharge has been diagnosed by the method of combined infrared thermograph and oil chromatographic analysis and the defect property and location has been judged accurately. The combined use of two kinds of on-line detection technology can avoid a serious equipment damage accident successfully.
