Product Details

The Megger FRAX101 Sweep Frequency Response Analyzer (SFRA) detects potential mechanical and electrical problems that other methods are unable to detect. Major utilities and service companies have used the FRA method for more than a decade.

 

The measurement is easy to perform and will capture a unique fingerprint of the transformer. The measurement is compared to a reference fingerprint and gives a direct answer if the mechanical parts of the transformer are unchanged or not. Deviations indicate geometrical and/or electrical changes within the transformer.

 

The Megger FRAX101 Sweep Frequency Response Analyzer detects problems such as:

  • Winding deformations and displacements
  • Shorted turns and open windings
  • Broken clamping structures
  • Core connection problems
  • Partial winding collapse
  • Faulty core grounds
  • Core movements
