Abstract

In this work the trends of a peak-time-and-frequency spectrum of vibrating signals for separate frequency strips and results of forecasting of development of defects of the hydrounit for identical time intervals are compared at different parent wavelets, like Dobeshi, Meyer and Bettla-Lemare. It is established that despite certain difference of these trends, the hierarchy of indicators of reliability of the reasons of vibration does not change.
