Product Description

Product Description

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.

Functional Features

1. The frequency sweep method is used to measure the characteristics of transformer windings. Without hanging or disassembling the transformer cover, the amplitude frequency response characteristics of each winding are detected to accurately measure the distortion, bulging, or displacement of the winding for 66kV and above transformers.
2. The measurement speed is fast, and the measurement time for a single winding is 1-2 minutes.
3. The frequency accuracy is very high, with a frequency accuracy of 0.001%.
4. Adopting digital frequency synthesis for higher frequency stability.
5. Using a 5000V voltage isolation to fully protect the safety of the testing computer.
6. The instrument has an oscilloscope function, which facilitates real-time monitoring and testing of the situation.
7. 9 curves can be loaded simultaneously, and the relevant parameters of each curve are automatically calculated and diagnosed for the deformation of the winding, providing diagnostic reference conclusions.
8. The analysis software used has powerful functions, and the software and hardware indicators meet the power industry standard DL/T911-2016 and the international electrical standard IEC60076-18.
9. Adopting the Windows platform, compatible with Windows 2000/Windows XP/Windows 7/Windows 8/Windows 10/Windows 11.
10. The software management function is powerful, fully considering the needs of on-site use. The measurement data is automatically saved and exported to generate Word test reports (corresponding Office software needs to be installed) or JPG picture reports, so as to facilitate users to produce test reports.
11. The software has a high degree of intelligence, and after the input and output signals are connected, all measurement work can be completed with just one key press.
12. The software interface is concise and intuitive. The menu for analysis, storage, report export, printing, and other functions will automatically pop up only after completing the current step, making it more convenient.
