Discrimination Between Radial Deformation and Axial Displacement in Power Transformers Using Analysis of Electromagnetic Waves

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...
