In recent years, the electromagnetic wave application has been proposed for the detection of mechanical defects in power transformer windings. After detection of a defect, the determination of defect type is the next stage of monitoring. In this paper, a comparative method is presented to discriminate between radial deformation and axial displacement in power transformer high-voltage winding using...
In this paper, three monitoring stages of detection, localization, and extent determination of radial deformation in power transformer winding using stationary ultra-wideband antennas, are investigated. For this purpose, two types of radial deformation are implemented on the actual transformer high-voltage winding. The first type is a modeled bulgy mechanical deformation, which its extent and reversibility...
