II. Product Characteristics

1. The technical performance is completely in line with national standard DL/T 911-2004 "The frequency response analysis of the deformation of the power transformer winding";

2. Use high -performance embedded processing chips, digital narrow belt filtering and other technologies to effectively suppress industrial frequency and high -frequency interference;

3. You can use wired network and wireless WIFI (split machine) to connect the tester to facilitate the use of on -site measurement;

4. The scanning range is from 1kHz ~ 2000kHz, which can flexibly select the frequency sweeping method to facilitate data comparison analysis;

5. Fast measurement speed, an average frequency point of 1,000, the measurement time does not exceed 1 minute;

6. The all -in -one machine uses high reliability industrial computers with a screen resolution of 1024x800, which is clear and delicate in display effect;

7. Multiple maps and data results display, such as frequency diagrams, differential curves, differences of rainbow bars, etc., the curve height adaptive adjustment can help details observation;

8. The main functions of the system are completed in a operation interface for convenience for user operations;

9. The test data can be "sealed" to protect the data, which is convenient for subsequent vertical comparison;

10. Support test data report generation and print output;

11. Short -circuit protection to ensure that the instrument is not damaged in the case of short circuit during wiring.
