UHV-311 Sweep Frequency Response Analyzer

Product Introduction

The transformer winding deformation tester is based on the measurement of the characteristic parameters of the internal winding of the transformer, and uses the internal fault frequency response analysis (FRA) method currently being developed in developed countries to accurately determine the internal faults of the transformer.

Product Features

1. Advanced DDS Core Technology
Dedicated digital high-speed scanning (DDS) detects:
Mechanical deformations (distortion/bulging/displacement/tilting)
Electrical faults (inter-turn shorts, phase-to-phase contact faults

2. High-Fidelity Acquisition System

SoC-controlled architecture with MIL-spec components

Dual-channel 16-bit A/D sampling (≥99.5% repeatability)

Field Validation: Tap changer operations induce significant waveform deviations

3. Dual-Sweep Measurement Modes
Linear + segmented frequency analysis compatible with domestic technical standards

4. Non-Invasive Testing Protocol
Requires only busbar disconnection; eliminates transformer disassembly

5. Ergonomic Field Operation
Measurement-insensitive lead configuration; technicians operate safely atop tank

6. Standards-Compliant Output

Meets national amplitude-frequency specifications (GB/T 1094.18)

User-selectable axis scaling: Linear or logarithmic plots

7. Intelligent Signal Control
Software-auto-ranged ±10V output with adaptive sampling frequency

8. High-Resolution Scanning
0-1MHz linear sweeps with configurable resolution (0.25/0.5/1kHz steps)

9. AI-Driven Diagnostics

6-curve historical comparison with axis-specific analysis

Automated parameter calculation & winding deformation diagnosis

Expert diagnostic conclusions

10. Automated Reporting Suite

Environmental parameter logging

Measurement data archiving
