Analysis and suggestion on the chromatographic detection of inverted oil immersed current transformer

Abstract

The detection and analysis of oil chromatography is the most effective method to detect the internal defects of the transformer, but the problems in design, manufacture and other aspects have limited the on-site detection. On the analysis of the Jiangsu power grid oil-immersed current transformer oil dissolved gas testing data and the collapse of the inspection, the effectiveness of the gases dissolved in transformer oil testing technology and limitations are studied, and related suggestions are put forward.
