Applicative Study on Gas Chromatography of Dissolved Gases in Oil
With the development of the economy,there are higher requirements for online monitoring technology of power equipment.As the hub of the power system,online monitoring of power transformers is particularly important.Online monitoring and analysis of dissolved gases in power transformer oil are important detection methods for diagnosing the op-erating status of the main transformer and internal overheating,discharge and other defects.This paper first describes the principle of gas chromatography and its application in the monitoring of dissolved gases in oil.It second reports gas chro-matography analysis of the dissolved gas hydrogen in a 220 kV transformer oil that exceeded the standard,and fault diag-nosis and countermeasures carried out based on the analysis result.
