On July 17th, 2012, PONOVO self-innovated transformer winding deformation tester successfully passed the technical tests and won the experts’ appraises.
The transformer winding deformation means that the power transformer windings’ axial or radial dimension changes in the roles of mechanical power or electric power. The deformation shows winding partial distortion, bulge or phase displacement, etc. The tester, based on DL/T911-2004 standard, is used to check the windings’ amplitude-frequency response characteristics and compares the results in vertical or horizontal comparison. According to the change situation of the characteristics, the tester judges the possible deformation of the transformer. This is the new innovation in primary injection test system for PONOVO. It will meet the market requirement effectively.
