Abstract

Taking the on-site winding deformation measurement of the first domestic 1 000 kV ultra high voltage transformer for example

the frequency response analysis（FRA）and the short circuit reactance（SCR）method are used to synthetically measure the winding deformation of the ultra high voltage transformer.The characteristics

on-site testing techniques and measurement results of both methods are analyzed.Consequently

the reliability and accuracy of transformer winding deformation diagnosis are effectively improved with the synthetic winding deformation measurement.
