YTC3223 Transformer Winding Deformation TesterDarui Electric recommendsProduct Features:
1. USB communication interface between PC and instrument.
2. Automatically generate Word electronic documents for saving and printing.
3. The computer generates electronic documents (WORD) from test results.
4. Signal output amplitude can be adjusted via software, peak ±10V.
5. Acquisition control uses high-speed, highly integrated microprocessor.
6. Finished circuit board with special surface treatment, resistant to water and harmful gas contamination.
7. Laptop and measuring instrument powered by isolated power supply to eliminate external interference.
8. High-resolution dB measurement, dual-channel 16-bit A/D (field test changing tap changer shows obvious output change).
9. Use of high-stability components; for repeated tests on the same phase, measurement repeatability is above 99.5%.
10. The instrument has dual measurement system functions: linear sweep measurement and segmented sweep measurement, compatible with the two current domestic technical schools of measurement modes.
11. Amplitude-frequency characteristics comply with national technical indicators for amplitude-frequency characteristic testers. The horizontal axis (frequency) has both linear and logarithmic scales, so the printed curve can be either linear or logarithmic, users can choose according to actual needs.
12. Fully meets the technical conditions of the electric power standard DL/T911-2004 "Frequency Response Analysis Method for Power Transformer Winding Deformation".
13. The hardware mechanism uses DDS dedicated digital high-speed sweep technology (USA). Through testing, it can accurately diagnose faults such as winding distortion, bulging, displacement, tilting, inter-turn short circuit deformation, and phase-to-phase short circuit.
14. Automatic analysis system for test data. Horizontal comparison: compare winding similarity among phases A, B, and C, results: ① Very good consistency ② Good consistency ③ Poor consistency ④ Very poor consistency. Vertical comparison: compare original data with current data for same phase A-A, B-B, C-C for winding deformation, results: ① Normal winding ② Slight deformation ③ Moderate deformation ④ Severe deformation.
Product Introduction: The YTC3223 Transformer Winding Deformation Tester quantifies the response changes of internal transformer winding parameters in different frequency domains. Based on the magnitude of change, amplitude and region of frequency response change, and trend of frequency response change, it determines the degree of change in the internal transformer winding. Then, based on the measurement results, it can judge whether the transformer has been severely damaged and whether major repair is needed.
