Main technical specifications of the Transformer Winding Deformation Tester (Frequency Response Method):
6. Test host to PC interface: USB or network.
7. Signal source: The instrument comes with one channel signal output as the sweep excitation signal; the signal output is a standard sine wave, the output amplitude can be adjusted via software, maximum amplitude ±10V, output impedance 50Ω.
8. Two acquisition channels: one for acquiring the excitation signal, one for acquiring the response signal, used to calculate the transfer function.
9. Sweep mode: Linear or logarithmic distribution sweep measurement.
10. Sweep frequency accuracy: The frequency accuracy of the sine signal output by the signal source is no greater than 0.01%.
11. Sweep measurement frequency points: Fixed mode or user-defined.
12. Complies with national power industry standard: DL/T911-2004.
Main features of the test analysis software:
13. Based on Windows platform, compatible with Windows 2000/Windows XP/Vista/Win7.
14. Uses Access database to save test data, making data management simple and convenient.
15. Can load up to 6 curves simultaneously; relevant parameters of each curve are automatically calculated, and the deformation of the winding is automatically diagnosed, providing a reference diagnosis conclusion.
16. The software has powerful management functions, fully considering the needs of field use; it automatically saves environmental condition parameters to provide a basis for transformer winding deformation diagnosis. Measurement data is automatically saved, with color printing function, convenient for users to generate test reports.
17. The software is highly user-friendly; most measurement conditions are options, requiring minimal input on site, making it more convenient for users.
18. The software is highly intelligent; after connecting the input and output signals, only one button press is needed to complete all measurement tasks.
19. The software interface is simple and intuitive.
