Abstract :
The on-line monitoring of transformer winding radial deformations using Ultra-Wideband (UWB) sensors and Discrete Wavelet Transform (DWT) has been presented in this paper. The measurements on a simplified model of the transformer winding demonstrate the high sensitivity of the proposed method to detect the winding radial deformation.
