Product Introduction
The UHV-310 Sweep Frequency Response Analyzer is designed to measure the characteristic parameters of transformer windings. It utilizes the Frequency Response Analysis (FRA) method to accurately diagnose internal transformer faults. The analyzer is effective for detecting issues such as inter-turn and phase short circuits, coil displacement, and deformation due to electromagnetic tension.

Product Features
1. Utilizes DDS digital high-speed frequency sweeping technology for precise fault diagnosis.
2. Features a highly integrated microprocessor with high-speed dual-channel 16-bit A/D sampling, ensuring a measurement repetition rate above 99.5%.
3. Offers dual measurement systems: linear frequency sweep and segmented frequency sweep.
4. Tests can be conducted without disassembling the transformer, reducing labor intensity.
5. Allows flexible signal input and output lead placement without affecting results.
6. Meets national technical indicators for amplitude-frequency characteristics.
7. Automatically adjusts signal output amplitude and sampling frequency.
8. Provides a variety of frequency linear sweep measurement functions with a sweep frequency up to 1MHz.
9. Includes historical curve comparison analysis and an expert intelligent analysis system for automatic diagnosis.
10. Features powerful software management for automatic data analysis and report generation.
