| Abstract: | Over the years the analysis of gas in oil used intransformer has been developed into a valuable tech-nilque in transformer diagnostic.The compositions ofthe gas dissolved in the oil are determined by means ofgas chromatography. On the basis of the concentrationof the gases and the kind of oil it can be establishedwhether the phenomenon should be classified as anelectrical or a thermal defect.The gas-extraction apparatus, multi-columns au-tomatic switching of chtomatogtaphy,sample injectingunit and analysis system have been described.H_2,CH_4,C_2H_2,C_2H_4,C_2H_6,C_3H_8,C_3H_8,CO,CO_2,N_2,andC_3,C_4 gas dissolved in the oil can be analysed. |
