Abstract
This paper presents a thermal model to predict the top oil and hot spot temperatures of a transformer. The model is applied to 2500 kVA ONAN (without external cooling) distribution transformer equipped with thermo-couples and tested at varying load. A non linear least square algorithm is used based on measurements to determine the model parameters. The model showed good results.
