Case Analysis of Abnormal Dielectric Loss of Transformer Bushing
In this paper,two cases of abnormal dielectric loss of 110 kV transformer bushing are analyzed.The possible defects of bushing are analyzed by combining oil chromatography,insulation resistance,10 kV conventional dielectric loss,high voltage dielectric loss and FDS test.One case of bushing is disassembled and checked to find out the cause of the defect.This paper can provide ideas and references for finding hidden defects of transformer bushing.
