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.

תכונות מוצר

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)
