In this paper, transformer thermal and loss of life models was studied. Based on the thermal model adopted by International Standards, small improvements to increase model accuracy are presented and a comparative study of resulted accuracy under different load and ambient temperature profiles was performed.

Key words: Transformer thermal, loss of life models, estimate thermal parameters.
