Abstract :
This work presents a methodology for distribution transformer rating selection and management. Measured or estimated daily load profiles are used to determine the transformer´s loss of life. Loss of life values are obtained for a number of transformers and are stored together with the corresponding load profiles in a database of patterns. The expected loss of life for a transformer not included in the database is obtained by comparing the transformer´s actual load profile to the ones stored in the database
