This paper presents a proactive maintenance scheme for fault detection, diagnosis and prediction in electrical valves. The proposed scheme is validated with a case study, considering a specific valve used for controlling the oil flow in a distribution network. The scheme is based in self-organizing maps, which perform fault detection and diagnosis, and(More)
This paper presents a proactive maintenance scheme for the detection and diagnosis of faults in electrical valves. In our case study, these actuators are used for controlling the flow in an oil distribution network. An embedded system implements selforganizing maps for the detection and classification of faults that lead to deviations either on torque, or(More)
