Product Overview: Vanguard VFRA-25 Transformer Sweep Frequency Response Analyzer
Vanguard VFRA-25 Transformer Sweep Frequency Response Analyzer
The Vanguard VFRA-25 is a power transformer frequency sweep response analyzer that can be used to perform frequency response measurements on power transformers in accordance with the C57.149-2012 and IEC 60076-18 standards. The VFRA-25 is bundled with analysis software that can graphically compare test results and provide correlation analysis per the IEEE C57.149-2012 and DL/T 911-2004 standards, allowing users to quickly assess the mechanical and electrical integrity of the transformer under test.
Features:
The VFRA-25 detects the mechanical or electrical changes of a transformer by comparing their frequency response measurement fingerprints. This comparison can be used to detect power transformer problems such as:
- Shorted turns or open windings
- Winding displacements or deformations
- Core movements
- Winding connection problems
- Broken clamping structures
