FRA500 Sweep Frequency Response Analyzer

Transformer Mechanical Integrity Diagnostic System

Description

The FRA500 confirms the mechanical integrity of transformers by comparing frequency response with previously known results. Every transformer has a unique frequency response system that changes if the mechanical geometry is altered due to physical movement, transportation, or high fault currents.

Applications

  • ✓ Core movements detection
  • ✓ Shorted turns or open windings
  • ✓ Winding displacements or deformations
  • ✓ Winding connection problems
  • ✓ Broken clamping structures
  • ✓ Faulty core grounds
  • ✓ Core connection problems
