Abstract This paper presents a residual life prediction method that combines a self - diagnostic evaluation of a transformer with An Approach to Power Transformer Asset Management Using Health Index. The asset management method analyzes the health of the transformer through a variety of precise diagnoses and predicts the remaining service life. The self-diagnostic evaluation analyzes the soundness of the electrical equipment and proposes precise diagnosis and emergency repair. By combining the self-diagnostic evaluations with the asset management, more accurate soundness analysis and residual life prediction can be achieved than before. Also, by changing evaluation score of the self-diagnostic, confirm that the causality between health and the life of the transformer.
