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.
