I. Introduction:

Our company has designed the frequency response analyzer SFRA-II, which can use two methods to detect the deformation of the transformer at the same time. One is the sweep frequency response analysis method, the other is low-voltage short-circuit impedance method. Using two methods can effectively reduce incorrect judgments.

SFRA-II Transformer Winding Deformation Tester follows the national power industry standards DL / T911-2004 and DLT 1093-2008, and can be used for IEC60076-18-2012 and IEC60076-5-2006.

II.Main Features

1. The Sweep Frequency Response Analyzer uses the advanced technical of DDS;
2. The SFRA uses the high speed and advanced microprocessor to design;
3. The Transformer Winding Deformation Tester  adopts AD chip of 16 bits;
4. The Sweep Frequency Response Analyzer adopts seven inch LCD touch screen of which the brightness can be adjusted;
5. With thermal printer of which the print thick can be adjusted;
6. The The Sweep Frequency Response Analyzer can store 120 groups of FRA data, 50 groups of SCI data and 30 groups of SCI data, which could be read to current screen or upload to the PC;
7. SPRA has PC software,by which we can upload data ,test, analyze data, print data, or create word document;
8. The Sweep Frequency Response Analyzer uses USB2.0 to connect to the device.
