HZ-600A Transformer SFRA Sweep Frequency Response Analyzer Price

HZ-600A Transformer SFRA Sweep Frequency Response Analyzer is used for power transformers with a voltage rating of 6 kV and above, as well as other transformers with specialized applications. Power transformers are inevitably vulnerable to the impact of fault short-circuit currents or physical collisions during operation and transportation. These forces can cause instability in the transformer windings due to the powerful electrodynamic forces generated by the short-circuit currents, potentially leading to permanent deformations such as local distortion, swelling, or dislocation, which can severely affect the safe operation of the transformer.Deformation of transformer windings is assessed using the frequency response analysis method, in accordance with the national standard DL/T911-2016/IEC60076-18 for the electric power industry. This method involves detecting the amplitude-frequency response characteristics of each transformer winding and making vertical or horizontal comparisons of the results to determine potential deformation based on changes in the amplitude-frequency response characteristics.

HZ-600A Transformer SFRA Sweep Frequency Response Analyzer

I.Main Functions And Features

1.The characteristics of transformer windings are measured using the frequency sweep method. Deformations such as distortion, swelling, or displacement in transformers rated 6 kV and above are detected by measuring the amplitude-frequency response characteristics of each winding, without the need to lift the transformer enclosure or disassemble the transformer.
2.Quick measurement: testing a single winding takes less than 2 minutes.
3.High frequency accuracy: greater than 0.001%.
4.Digital frequency synthesis provides higher frequency stability.
5.5kV voltage isolation fully protects the testing computer's safety.
6.The system can load 9 curves simultaneously, automatically calculate the parameters for each curve, and diagnose winding deformations, providing a reference diagnostic conclusion.
7.The analysis software has powerful functions, and both software and hardware meet the national standard DL/T911-2016/IEC60076-18.
8.The software interface is user-friendly with a high level of intelligence. After setting the parameters, a single click completes all measurements.
9.The software interface is clear and intuitive, with menus for analysis, saving, report export, printing, etc.
10.The software is compatible with Windows 2000/Windows XP/Windows 7/Windows 8/Windows 10.
11.A database is used to store test data, making data management concise and easy.
12.The system can load 9 curves simultaneously, automatically calculate the parameters for each curve, and diagnose winding deformations, providing a reference diagnostic conclusion.
13.The software management function is powerful and meets the on-site usage needs. Measurement data is automatically saved and exported as a Word document (requires relevant Office software) or a JPG report for easy report generation.
14.The software is highly user-friendly, with most measurement conditions as selectable options, reducing the need for manual input and simplifying operation.
15.The software is highly intelligent: after connecting the input and output signals, a single click completes all measurements.

16.The software interface is concise, intuitive, and practical.
