Signal analyzer FRANEO 800

Description

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 sweep frequency response analysis (SFRA) principle and measures the electrical transfer function over a wide range of frequencies. With our FRANEO 800 you can improve your transformer reliability, reduce maintenance costs and prevent expensive failures.

Small details make a big difference

FRANEO 800’s overall measurement principle is based on a comparison of an actual measurement and its fingerprint in order to allow detection of deviations. Therefore, it is vital that the measurement becomes reproducible which substantially depends on the connection technique used.

The specially designed clamps and wide flat braids guarantee a reliable test setup, making FRANEO 800 less sensitive to influences from its surroundings and also easier to use.

Key features:
– Extremely small and compact device guarantees optimum usability
– Innovative connection technique ensures high level of reproducibility
– Short measurement times due to the intelligent sweep algorithm
– Highest dynamic range in SFRA testing industry (> 150 dB)
– Fully compliant with the IEC 60076-18 and IEEE C57.149 standards

Applications:
FRANEO 800 can be used for transformer testing, after:

– a short-circuit event
– before and after transport
– an occurrence of high transient fault currents
– a significant change in the monitored values (for example, 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
