OMICRON / FRANEO 800

Sweep Frequency Response Analyzer

Any change in the stator winding of rotating machines is detected by analyzing the electrical network using the FRANEO 800 with Sweep Frequency Analysis (SFRA). A change in the electrical network of the rotor winding can lead to magnetic imbalance of the machine. By detecting electrical network changes, FRANEO 800 helps you to prevent any major damage of machine bearings.

Thanks to an innovative connection technique, the measurements are able to be reproduced and are easily compared. Even with little prior experience, the FRANEO 800 software is easy to use and provides you with support via connection diagrams and standard settings. It is also possible to fine-tune the measurement settings yourself, so that you can perform more sensitive measurements.

FRANEO 800 was developed for testing the mechanical and electrical integrity of power transformers after transportation or exposure to high fault currents. It uses the SFRA principle (Sweep Frequency Response Analysis) and measures the electrical transfer function over a wide range of frequencies.

FRANEO 800 detects winding defects and faults in the magnetic core - thereby helping to improve transformer reliability, reduce maintenance costs and prevent expensive failures.

Key features

Highest dynamic range in SFRA testing industry (> 150 dB)
Fully compliant with the IEC 60076-18 and IEEE C57.149 standards
Reproducible results thanks to an innovative connection technique
Guided workflow for test setup, execution and assessment for easy analysis without expert knowledge
Fast measurement times due to the intelligent sweep algorithm

Applications

FRANEO 800 can be used for transformer testing, after:

a short circuit event
before and after transport
occurrence of high transient fault currents
a significant change in the monitored values (e.g. combustible gases) or a safety shutdown

The following tests can also be performed:

Routine transformer condition measurement
Verification of unusual events determined during conventional testing
