The FRA 5310 is a diagnosis instrument for the detection of mechanical distortions of transformer winding. These distortions can be caused by electro-dynamical forces which appear during short-circuits or by transportation damages during movement.The Sweep Frequency Response Analysis method is based on winding transfer function measured in a wide range of frequency. The system records the transformers _frequency response fingerprint €. Even small winding movements or distortions will cause legible change of transfer curve, which can be detected. Special active measuring probes minimise the influence of test object connecting and earthing which results in reproducible measurements.
