Physical phenomena leading to the decline in the technical condition of turbogenerators are discussed. Some contributions are suggested to explain the mechanism of stator core failure. Results of video-scope observations are presented which were made in order to supply documentary evidence for the phases of developing stator failures. A list of problems is given the solution of which will allow successful reconstruction and appropriate operation of turbogenerators in service and will create a basis for designing faultless turbogenerators.
