The aim of this study is to develop a high-speed fault transducer and, based on it, to create an automated system for monitoring and repairing faulty insulation of winding wires in electrical equipment. The fault transducer under development is based on a gas discharge process that occurs between a high-voltage electrode and a grounded wire conductor in a damaged insulation segment. Oscillographic measurements show that there is a complex signal that appears on the fault transducer when a damaged insulation segment is passed through it. The basic patterns of electrodeposition of dielectric films onto metals were determined. The conditions of this process were optimized. The features of the above-mentioned signal that can be used to monitor the number of faults and lengths of damaged segments, as well as the features of the deposition of dielectric films onto metals were justified. Based on these features, a faulty wire insulation repair process was developed and can be controlled.
