This paper presents an algorithm for the winding temperature change estimation and the hot spot temperature determining of an oil filled power transformer. The proposed algorithm is based on the functional relation between the change of winding resistance and the measured oil temperature. The temperature changes approximation is based on the method of least squares. The proposed method is applied in the software for a field test instrument and verified by the field experiments.
