FRAX-101
SWEEP FREQUENCY RESPONSE ANALYZER
The FRAX-101 Sweep Frequency Response Analyzer (SFRA) detects potential mechanical and
electrical problems that other methods are unable to detect. The FRA method have been used by
major utilities and service companies for more than a decade. The measurement is easy to perform
and will give a unique “fingerprint” of the transformer. Knowing the internal status of your transformer
allows you to operate at maximum load without compromising reliability.
FRAX-101 detects problems such as:

Winding deformations and displacements
Shorted turns and open windings
Loosened clamping structures
Broken clamping structures
Core connection problems
Partial winding collapse
Faulty core grounds
Core movements
Hoop buckling
Collecting fingerprint data using Fre-
quency Response Analysis (FRA) is
the easy way to detect electro-
mechanical problems in power trans-
formers and an investment that will
save time and money.
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.
