Abstract :
In this work a novel algorithm to evaluate the condition of power transformers is presented. The algorithm evaluates the condition of the equipment via dissolved gas analysis. Firstly, the condition is evaluated using the gas ratio of IEC and the Triangle of Duval. Then, the vector of possible disorders is used as input of a Type-2 Fuzzy Logic System. In this way, the condition is obtained and expressed in words easy to understand by the maintenance personnel. The efficiency of the algorithm has been tested with field data obtained in the bibliography. The validity of the algorithm is shown by means of an example.
