| Zusammenfassung: | The invention relates to a method of utilizing the vibration waveform for detecting the state of the transformer winding. A transformer winding is viewed as a mechanical system; and if the winding is loosened or deformed, the mechanical characteristics of the winding changes, thus the corresponding mechanical characteristics of the transformer winding under the action of the impulse current are detected and the loosening and deforming condition of the transformer winding can be detected sensitively. |
