THE OMICRON FRANEO 800, THE NEXT GENERATION FOR A RELIABLE CORE AND WINDING DIAGNOSIS
OF POWER TRANSFORMERS
Sweep Frequency Response Analysis (SFRA) is a tried and tested method for Transformer Testing and has become a widely accepted test since the introduction of IEC 60076-18. Mechanical or electrical stresses due to transportation or mains failures can be detected well in advance of the production of catastrophic failures further down the line
SFRA performs measurements in a frequency domain. It is robust against broadband and narrowband noise
and thus, it is able to achieve a high signal-to-noise ratio. SFRA is a non-invasive measurement method
and based on a comparison of actual and reference measurements.
With the Omicron FRANEO 800 you can detect defects as well as faults in the magnetic
core, the winding assembly, and the clamping structures of power transformers. The Omicron FRANEO 800 injects a sinusoidal excitation voltage with a continuously increasing frequency into one end of the transformer winding and measures the signal returning from the other end.
Transformers have their own unique frequency response. Since SFRA is a comparative method, it is vital that
measurements become reproducible. This is the only way to guarantee that deviations between an actual
measurement and its fingerprint can be related to defects within the observed transformer.
With Omicron FRANEO 800 you can detect defects as well as faults in the magnetic core, the winding assembly, and the clamping structures of power transformers and as a result you can improve the reliability of your transformers, reduce maintenance costs and, most of all, avoid unexpected and expensive outages.
