Analysis of Maintenance in Transformers Based on a Fuzzy Logic Method

In this paper, an evaluation of Power transformer assessment is developed in order to determine when maintenance is feasible from the point of view of economics and aging of the asset. For this purpose, a model of health condition and failure rate is used and then fuzzy logic method is applied for some other considerations needed to stablish the action required in the transformer along the simulation. This is a new approach for estimating the need of maintenance in a power transformer.
