The SG7201 is a diagnosis instrument for the detection of mechanical distorti*** of transformer winding. These distorti*** can be caused by electro-dynamical forces which appear during short-circuits or by transportation damages during movement.
The Sweep Frequency Resp***e Analysis method is based on winding transfer function measured in a wide range of frequency. The system reco*** the transformers “frequency resp***e fingerprint”. Even ***all winding movements or distorti*** will cause legible change of transfer curve, which can be detected
A powerful, easy-to-use operation and analysis Windows software runs on this touch screen controlled measuring instrument. Special active measuring probes minimise the influence of test object connecting and earthing which results in reproducible measurements.
