Abstract :
An ANN based implementation of Oommen´s curve to study the online estimation of moisture in paper insulation of transformer using temperature and moisture in oil as input is presented. It is based on a multilayer feed forward network (MLP) with one hidden layer in addition to input and output layer. The implementation, analysis, results and applications of the scheme is discussed. The results confirm that the estimated output of the ANN follow the desired output of the Oommen´s curve very closely. It is found that the error remains within ±2% of full scale for temperature of 40°C to 100°C. The implementation has the potential to diagnose the incipient fault in real time based on estimation of moisture in paper insulation.
