Impedance tester HZ2612

for transformersindustrialfor power systems

The Transformer Short Circuit Impedance Tester is engineered to provide accurate and reliable measurements of short circuit impedance, allowing users to evaluate the transformer’s performance under various load conditions. With its user-friendly interface and advanced technology, this tester simplifies the testing process, making it accessible for both seasoned professionals and newcomers in the field. The power transformer occurs in the turbine, the short circuit between the turbine, the phase, or the collision during transportation during the test, causing the relative displacement of the coil, and the deformation of the coil due to electromagnetic pulling force during the short circuit and failure during the operation. The parameters change, which affects and changes the original impedance characteristics of the transformer. Article 15.2 of the [2000] Document No. 589, "No. 589" issued by the National Electric Power Corporation clearly stipulates that "110kV and above voltage -level transformers should do low -voltage and short -circuit impedance tests before the factory and put into production Or use the frequency response method to retain the original record. "15.6 stipulates that" the transformer should do low -voltage short -circuit impedance testing or use frequency response test winding by the short -circuit short circuit in the near area, and compares it with the original records. It can be carried out after judging the transformer without failure. "The low voltage impedance test can accurately reflect the changes in the impedance value of the transformer before and after the winding.
