Introduction was made to the ifnite element method of analog thermal circuit model of traditional transformer internal thermal ifeld, and on this basis, average oil temperature, sun radiation etc conditional parameters were added to carry out improvement for the original model. The optical ifber grating temperature measurement system was used to carry out site temperature rise test for sample transformer. This paper car-ried out comparison of thermal circuit amended model calculation result with several transformers actual tested temperature rise data. The result veriifes the correctness of the thermal circuit amended model.
