FIELD: electric engineering.
SUBSTANCE: isolator is affected by means of oscillations exciter and signal of isolator response is estimated. As response signal, spectral density of vibration power is registered, which vibration occurs as a result of vibration effect. On appearance or absence in spectrum of vibrations power density of at least one additional peak, having comparable level to peak of spectral density of power of main tone, decision is taken respectively about unsatisfactory or satisfactory state of isolator.
EFFECT: simplified diagnostics of technical state.
