Estimating the temperature distribution in transformer components in
the design stage and during the operation is crucial since temperatures
above the thermal limits of these components might seriously damage
them. Thermal models are used to predict this vital information prior to
actual operations. In this study, a two-dimensional, steady-state model
based on the Finite Difference Method (FDM) is proposed to estimate
the temperature distribution in the three-phase, SF6 gas insulatedcooled
power transformer. The model can predict the temperature
distribution at the specific discredited locations in the transformer
successfully. This study also compares predicted temperatures of the
model proposed in this study with the results of the previous study
which is based on Finite Element Method (FEM) and the results of the
research performed by the designers of the transformer. The results
show that FDM model proposed in this study can be used to estimate
the temperature distribution in the transformer with an acceptable
accuracy and can be an alternative of the previous study which is based
on FEM.
