Sweep frequency response analyzer
More than a Test Device
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.
FRANEO 800 is operated with the Primary Test Manager™ (PTM) software, the ideal solution for diagnostic testing, condition assessment and easy data management.
PTM automatically generates test plans based on the nameplate data and in accordance with international standards. Existing results can be easily imported in order to ensure a flexible, device-independent comparison. In addition, PTM offers automatic result assessment and smart features, such as the visualization of typical influences for deviations.
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
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
Short measurement times
The implemented algorithms enable more precise measurement results in less time by firstly performing a broadband measurement and then focusing on the critical frequency areas.
Widest dynamic range
FRANEO 800 provides the widest dynamic range in the SFRA industry (> 150 dB). In combination with the variable output voltage (0.1 Vpp to 10 Vpp) the signal-to-noise ratio can be enhanced, and the influence of interference reduced.
With the powerful integrated battery, you can also perform tests in environments without a power supply. This makes FRANEO 800 ideal for commissioning and troubleshooting tasks.
The integrated ‘Ground Loop Check’ verifies the test setup and makes sure that the grounding braids are properly connected. It gives you a “Pass/Fail” assessment and either allows or prevents you from continuing with your measurement.
