FIELD: measurement technology.
SUBSTANCE: origin and intensity of oscillation process in blading of rotor wheel of turbine machine are judged from relation of average meanings of results of transformation of radial spaces along all the blades subject to control when those relations are registered during mode when there was no breakage and surging detected and oscillations of blades which correspond to these phenomena as well as during current mode, which oscillations were received at the same angular positions of locks of blades, when locks of blades found themselves in opposition to sensitive member of transformer.
EFFECT: improved reliability of measurement.
