Power transformers are some of the most vital components in
today’s transmission and distribution infrastructure. Transformer failures cost enormous amounts of money in unexpected outages and unscheduled maintenance. It is important to avoid these failures and make testing and diagnostics reliable and efficient.
The FRAX series of sweep frequency response analyzers (SFRA) detects mechanical and electrical changes of the core and winding assembly of power transformers. Major utilities and service companies have used the FRA method for more than a decade and the method is covered in international standards. The measurement is easy to
perform and will capture a unique fingerprint of the transformer.
The measurement result 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.
