This paper analyses transformer loss of life, attending to the realistic variability of both structural and functional parameters. The article begins with the modelling of load and ambient temperature profiles by means of chronological series theory. A simple additive model is proposed and validated with realistic data. Loss of life resulting from probabilistic functional and structural parameters is analysed through a sensitivity study.


Key words: Transformer thermal, estimate thermal parameters.
