In order to master the condition of power transformer in real time, a condition assessment method based on the information of SCADA system is presented. According to the power transformer's internal physical laws, the electric quantity and non-electric quantity provided by the SCADA system, and the tracking estimation of the electric equivalence parameters and the temperature change of the transformer, the method combined with the fuzzy synthetic evaluation theory can realize the real-time and fast evaluation of the transformer finally. Actual examples show that the proposed method provides a new approach to evaluate the condition of transformers in the practical running
