This article is a short circuit detection circuit development in a series of winding motor connected to the FPGA with a three-phase induction type for roll krongkrarok wired with power KW 0.37 and coordinates coordinates are 2.2 KW, which is a star with a normal condition in storage and wrong (short circuit the phase A. B three-phase circuit and short circuit the phase C) and then using the wongchonkrong frequency bands over to filter the frequency range that could indicate malfunction due to a short circuit, and then calculates the signal flow. Use the method to find the tick split (Thresholds), based on artificial neural network. (Artificial Neural Networks: ANN), MATLAB and LabVIEW programming done on Perceptron to analyze for abnormalities, and then create circuits on FPGA Board test results indicate abnormalities had been must be up to 90%
