Abstract
A method for identifying asymmetrical vibrations during the operation of an electric device which is connected to a high-voltage grid: Operational noise of the electric device is detected using acoustic sensors which output measured values. The measured values and/or values derived therefrom are transmitted to a communication unit via a close-range communication connection and then transmitted to a data processing cloud via a far-range communication connection. The measured values and/or the values derived from the measured values are separated into frequency components by the data processing cloud using a Fourier transformation, thereby obtaining a frequency spectrum. Odd and even frequency components of the frequency spectrum are ascertained on the basis of a base frequency of the high-voltage supply grid and put into a ratio R relative to one another. The presence of asymmetrical vibrations is indicated if the ratio R exceeds a specified threshold.
