Omicron FRANEO 800

Advanced Diagnostic Capabilities:
The FRANEO 800 performs high‑resolution frequency sweep measurements and compares the results with reference “fingerprint” signatures to identify deviations, revealing changes in internal structures caused by transport, short‑circuit events, high fault currents, or ageing. With an industry‑leading dynamic range of over 150 dB and intelligent sweep algorithms, it delivers fast, repeatable, and highly accurate SFRA results.

Intuitive Operation:
Operation is simplified through integration with Primary Test Manager™ (PTM) software, which automatically generates test plans based on transformer nameplate data and international standards. PTM supports easy data management with importable historical results, automatic assessment features, and guided workflows for setup, execution, and analysis.

Portable and Field‑Ready:
Designed with field use in mind, the FRANEO 800 is extremely compact and lightweight, ensuring optimum usability and ease of transport. Its innovative connection technique with reliable clamps and flat braids enhances measurement reproducibility even in challenging substation environments.

Comprehensive Support:
Renting the OMICRON FRANEO 800 includes access to technical support for setup, PTM configuration, and troubleshooting, ensuring effective and efficient testing operations.

Trusted by Industry Professionals:
The FRANEO 800 is widely used by utilities, transformer manufacturers, and service providers globally for transformer diagnostics after transport, fault events, and as part of routine maintenance programs. Its high dynamic range, reproducibility, and compliance with international standards make it a trusted solution for SFRA testing.

The OMICRON FRANEO 800 is a cutting‑edge Sweep Frequency Response Analyzer (SFRA) designed for comprehensive diagnostic testing of power transformers. Using the proven SFRA principle, it measures the electrical transfer function over a wide frequency range to assess the mechanical and electrical integrity of transformer windings and cores. The FRANEO 800 helps improve transformer reliability, reduce maintenance costs, and prevent expensive failures by quickly detecting subtle changes or faults that other tests may miss.
