When researching electro-insulating materials, searching for new methods of diagnostics and prediction of the lifetime of those insulating materials assumes more and more importance. We are concerned with degradation process of insulating materials used for insulation systems of electric rotary machines windings by artificial intelligence. Our research is focused to residual lifetime prediction of this insulation system. Most usable methods of artificial intelligence are neural networks, fuzzy systems and genetic algorithms. In this contribution we are especially focused to use hybrid systems like fuzzy-neural networks. We have two main types of these networks. First is less difficult and there is used classical neural network with some no-fundamental changes. We only put on two blocks: block of fuzzyfication into the input and block of defuzzyfication into the output. There are some changes in number of neurons in input and output layers. The result is classical neural network with some changes, which works with fuzzy numbers. In the second type of fuzzy-neural network, there are particular neurons represented by fuzzy sets. There are many differences between this network and classical neural network. All the layers are converted for using as a completely fuzzy model. Modules of fuzzyfication and defuzzyfication are included too. We used back-propagation learning algorithm but converted for our need.
