摘要：
Questions on the joint application of various diagnostic methods in order to evaluate the technical state of the functional units of induction motors are examined. The possibility of using a set of methods of vibration monitoring and signature analysis of the stator current and external magnetic field in the start-up and steady-state modes of induction motors is assessed. The studies were conducted on an actual high-voltage induction motor of the induced-draft fan of one of the thermal power plants. During the study, a search was done for mechanical defects, dynamic eccentricity, and rotor winding faults. The results of the conducted studies were analyzed, and confirmation was done of the effectiveness and expediency of the methods of the joint application of vibration monitoring and signature analysis of the signals of the stator current and external magnetic field, in order to detect faults in the rotor winding and the mechanical components of the induction motors. © 2023, Springer Science+Business Media, LLC, part of Springer Nature.
