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.

Technical Features

1. High-Performance Core Control – Utilizes a high-speed, highly integrated microprocessor for precise data acquisition and control.

2. USB Communication – Supports direct USB interface connection to laptops for seamless data communication.

3. Wireless Bluetooth Connectivity – Enables wireless data exchange between instrument and laptop for flexible field operation.4. Advanced DDS Sweep Technology – Adopts digital frequency-sweep technology (USA) to accurately diagnose winding distortion, bulging, displacement, tilting, inter-turn short circuits, and inter-phase faults.

5. High-Resolution Dual-Channel Acquisition – Features dual-channel 16‑bit A/D with high-resolution dB‑value measurement for superior signal accuracy.

6. Software-Adjustable Output – Output amplitude adjustable via software, with peak output up to 10 V.

7. Automated Reporting – System automatically generates test reports in electronic Word format.

8. High Stability & Repeatability – Built with precision, high‑stability components; measurement repeatability exceeds 99.5% for the same winding phase.

9. Robust Hardware Design – Finished circuit boards are specially surface‑treated for resistance to moisture and corrosive gases.

10. Flexible Measurement Modes – Combines linear and segmented frequency‑sweep modes, compatible with mainstream domestic technical methodologies.

11. Compliant & Adaptable Display – Meets national technical standards for amplitude‑frequency characteristics; supports both linear and logarithmic frequency axes, allowing users to select the most suitable format for report printing.
