Abstract :
The asset management of any Transmission System Operator (TSO) cannot ignore the evaluation of the power transformers fleet. Even in the absence, to date , of any specific international guide or standard, every big electrical utility is adopting a home-made “Health Index”. An RI is developed to summarize in numerical form the transformers´ reliability for the purpose of evaluation, ranking and comparison. In the present paper the author will elucidate a new model that merge the evidences of periodic tests (DGA, furans, acidity, inductance, FDS, etc.) with the keraunic properties of a substation.
