METHOD FOR DETECTING TRANSFORMER WINDING STATE UTILIZING VIBRATION WAVEFORM

摘要

A method for detecting a transformer winding state utilizing vibration waveform. The transformer winding is regarded as one mechanical system, mechanical properties of which would change when the winding is loosening and deforming. The loosening and deforming of the transformer winding can be detected with higher sensitivity by detecting mechanical corresponding properties of the transformer winding under impact current.
