Sweep Frequency Response Analyzer Sfra Test in Transformer
Product introduction
Sweep Frequency Response Analysis (SFRA) is a powerful and sensitive method to evaluate the mechanical integrity of core, windings and clamping structures within power transformers by measuring their electrical transfer functions over a wide frequency range. SFRA is a proven method for frequency measurements.
The SFRA is a comparative method, meaning an evaluation of the transformer condition is done by comparing an actual set of SFRA results to reference results.
Features
1. The measurement speed is fast, the measuring time for a single winding is 1-2 minutes.
2. The frequency accuracy is very high,is 0.001%.
3. Digital frequency synthesis, higher frequency stability.
4. 5000V voltage isolation, fully protect the test computer security.
5.9 curves can be loaded at the same time, the relevant parameters of each curve can be calculated automatically, the winding deformation can be diagnosed automatically, and the reference conclusion of diagnosis can be given.
6.The analysis software has powerful functions. The software and hardware indexes meet the power industry standard DL/T911-2016 and the international electrical standard IEC60076-18.
7.Use Windows , compatible with Windows 2000 / XP/Windows 7 / Windows/Windows 10.
8.Uses the database to save the test data, the management of the test data is simple and convenient.
9.Software management function is powerful, fully consider the needs of field use, automatic measurement data saving, automatic export to generate Word version of the test report (need to install the corresponding Office software) or JPG picture report, convenient users out of the test report.
10.The software is high intelligence. After the input and output signals are connected, it only needs to press a key to complete all the measurement work.
11.Software interface is simple and intuitive, analysis, storage, report export, printing and other menus, only to complete the current step automatically pop up the next required menu, more convenient.
