Temperature Distribution in Core and Winding of a Transformer and Its Effect on Performance

Abstract

In order to reach the maximum power from a transformer and avoid thermal accidents, it is essential to carefully study its thermal behavior. This research is to apply some computational and analytical approaches in order to obtain a temperature distribution within the core and winding of a transformer. Hence its thermal behavior can be analytically and practically predicted. The aim is to optimize transformer operation under various load conditions during the extreme weather of summer season in the southern part of Iraq. The numerical scheme applied which is based on finite difference method has shown to be in good agreement with the empirical data measured on the external finned body of transformer.
