What is the SFRA (Sweep Frequency Response Analysis) test of a transformer?

The SFRA test of transformer, or Sweep Frequency Response Analysis, is a diagnostic tool used to assess the mechanical integrity of transformers by measuring the frequency response of its windings. This non-intrusive method detects changes in the transformer’s internal structure, which may indicate problems such as deformation, winding movement, or insulation failure. By applying a series of frequencies and analyzing the response, technicians can identify anomalies that could threaten transformer reliability. Globecore offers advanced solutions for performing SFRA tests, ensuring accurate results and effective monitoring of transformer conditions.
