Informative value of online monitoring of turbo generator technical condition parameters compared to visual inspection
Measurements of partial discharge amplitudes and spectral analysis of vibration at different times and often by different people are poorly informative, which are accepted in the practice of turbine generator diagnostics. The information content is much higher when both discharges and vibrations a...

| Summary: | Measurements of partial discharge amplitudes and spectral analysis of vibration at different times and
often by different people are poorly informative, which are accepted in the practice of turbine generator
diagnostics. The information content is much higher when both discharges and vibrations are measured at
the same point, this allows you to see both the synergy of “vibration phenomena and discharges” and
the reverse synergy of “discharges and vibration phenomena”. And the analysis of the distribution of
the magnetic field over the surface of the generator housing makes it possible to identify the result of
the “operation” of the discharges and vibration. To determine their effect on tires and current-carrying
elements of turbo generators the paper provides practical examples of determining defect zones using this
method and confirming them during visual and instrumental inspection during repairs. |
