Abstract

The purpose of this article is to analyse the different thermal models proposed in specialised bibliography for oil-immersed distribution transformers as well as their application domain. Improvements to increase transformer thermal model accuracy are presented and the validation for the introduction of each model improvement is based upon the simulation of several loading cycles.
