This work studies the feasibility of implementing a system for diagnosis in the field of electrical insulation based on ultrasonic noise and artificial neural networks. Such system, proved functional under laboratory conditions, extracts spectral information from the ultrasonic noise emitted by the corona discharges that occur in electric equipment and correlates it with degrees of pollution previously...
