In this paper, a new method is proposed for transformer dynamic loading capability assessment using fuzzy modeling. Firstly, the hot spot temperature is estimated by fuzzy thermal model and then is compared with the temperaturesobtained by measurement and IEEE thermal model. Afterwards, the method of dynamic loadability assessment is described and implemented by the fuzzy model. Comparison between the results obtained by the fuzzy thermal model and the IEEE model demonstrates the usefulness of the fuzzy model application.
