Abstract
The Doble M5100 is a robust and field proven instrument for detection of hidden fault in Power Transformer uses technique called Sweep Frequency Response Analysis (SFRA). SFRA is a tool that can give an indication of core or winding movement in Power Transformer this is done by performing a measurement, albeit a simple one, looking at how well a transformer winding transmits a low voltage signal that varies in frequency, Just how well the transformer does this is related to its impedance, the captive and inductive elements of which are intimately related to physical construction of transformer, Changes in frequency response as measured by SFRA technique may indicate a physical change inside the transformer, the cause of which then need to be identified and investigated. M5100 allow us to see inside the transformer and detect even suitable changes in the mechanical structure of the core and winding.
