FRANEO 800

FRANEO 800 is a state-of-the-art Sweep Frequency Response Analyzer (SFRA) designed to evaluate the mechanical and electrical integrity of power transformers. By analyzing the frequency response signature of the transformer windings, the system detects winding deformation, core movement, shorted turns, and mechanical displacements. It features high repeatability and advanced noise suppression, enabling accurate measurements even under substation conditions. FRANEO 800 complies with international standards such as IEC 60076-18 and IEEE C57.149, ensuring globally recognized diagnostic results. Its intuitive software provides automated assessment, trend comparison, and fingerprint analysis for long-term condition monitoring. Rugged hardware and optimized measurement speed make FRANEO 800 ideal for field testing, commissioning, and post-fault analysis.
