The transformer winding deformation tester quantifies the response changes of the transformer's internal winding parameters in different frequency domains, and determines the degree of change of the transformer's internal winding according to the size of the change value, the amplitude, area and trend of the frequency response change. It can then judge whether the transformer has been severely damaged and whether it needs major repairs based on the measurement results.
1) The technical performance fully complies with the national standard DL/T 911-2004 "Frequency Response Analysis Method of Power Transformer Winding Deformation";
2) Use high-performance embedded processing chips, digital narrowband filtering and other technologies to effectively suppress power frequency and high-frequency interference;
3) The tester can be connected to the tester using wired network and wireless WIFI (split machine), which is convenient for on-site measurement;
4) The sweep frequency range is from 1KHz to 2000KHz, and the sweep frequency mode can be flexibly selected to facilitate data comparison and analysis;
5) The measurement speed is fast, with an average of 1000 frequency points and the measurement time does not exceed 1 minute;
6) The all-in-one machine uses a high-reliability industrial computer with a screen resolution of 1024×800, and the display effect is clear and delicate;
7) A variety of graphs and data results are displayed, such as amplitude-frequency diagrams, difference curves, difference rainbow bars, etc. The curves are highly adaptively adjusted to facilitate detailed observation;
8) The main functions of the system are completed in one operation interface, which is convenient for users to operate;
9) The test data can be "sealed" to protect the data and facilitate subsequent longitudinal comparison;
10) Support test data report generation and print output;
11) Short circuit protection ensures that the instrument is not damaged in the event of an accidental short circuit during wiring.
