Modelling of on-line monitoring of transformer winding radial deformation using UWB sensors

Abstract

The radial deformation of transformer windings can be caused by mechanical or electromechanical forces. In this paper, a new monitoring method based on Ultra Wide Band (UWB) sensors, to detect the radial deformation of winding of large power transformers, is proposed. The proposed experimental set-up for this method has been modelled using CST (Computer Simulation Technology) software. The results show that the radial deformation of windings can be detected by the on-line monitoring of UWB waves.
