Zusammenfassung:	The invention provides a method for predicating the concentration of dissolved gas in transformer oil. The method comprises the following steps: acquiring historical concentration data of each characteristic gas of a transformer, historical oil temperature and historical load data; carrying out dimensionless treatment on the historical concentration data of each characteristic gas of the transformer, the historical oil temperature and the historical load data; carrying out correlation analysis on the data; constructing a model for predicating the concentration of the dissolved gas in transformer equipment oil; optimizing the model for predicating the concentration of the dissolved gas in the transformer equipment oil; predicating the concentration of the single characteristic gas dissolvedin the transformer oil. The method provided by the invention can be used for accurately predicating a change trend of the concentration of the gas dissolved in the oil and effectively identifying potential faults of transfor
