Title: Comparison between artificial neural networks algorithms for the estimation of the flashover voltage on insulators Keywords: High voltage insulators, polluted insulators, critical flash Abstract: This work attempts to apply Artificial Neural Networks in order to estimate the critical flashover voltage on polluted insulators. First, an ANN was constructed in MATLAB and has been trained with several MATLAB training functions. Then, an ANN was constructed in FORTRAN using an adaptive algorithm, in which the parameters of momentum and learning rate changed during the learning procedure, in order to optimize the training process. In each case the Artificial Neural Network uses as input variables the following characteristics of the insulator: the diameter, the height, the creepage distance, the form factor and the equivalent salt deposit density and estimates the critical flashover voltage.
