The transformer winding deformation tester is used to test the deformation of power transformers with voltage levels of 66kV and above and other special purpose transformer windings. During operation or transportation, power transformers are inevitably subjected to various faults, short-circuit currents, or physical impacts. Under the strong electric force generated by short-circuit currents, the transformer winding may lose stability, leading to permanent deformation phenomena such as local distortion, bulging, or displacement, which will seriously affect the safe operation of the transformer. This instrument adopts the frequency response analysis method to measure the winding deformation of transformers according to the national power industry standard DL/T911-2016 and the international electrical standard IEC60076-18. It detects the amplitude frequency response characteristics of each winding of the transformer and compares the detection results vertically or horizontally. Based on the degree of change in amplitude frequency response characteristics, it determines the possible deformation of the transformer winding.
This system consists of a measurement section and an analysis software section. The analysis section is completed by a laptop, and the measurement section is connected to the laptop through a USB cable.
