Fuzzy logic applied to PD pattern classification

A procedure is described for the application of fuzzy logic systems to the classification of partial discharge pulse patterns in terms of cavity or vo id size. The features employed in the pattern recognition task are those re lated to the form or shape of the partial discharge pulses and their associ ated apparent charge transfer Preliminary results, obtained with the fuzzy logic system on simple partial discharge sources, indicate a performance ap proaching that attainable with artificial neural networks.
