Transformer Mechanical Integrity Diagnostic System
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.
Fully compliant with IEC 60076-18 and IEEE C57.149-2012 standards.
