One of the most powerful and accurate tool for winding deformation detection in power transformers is Frequency Response Analysis (FRA). But the interpretation of FRA plots still needs a higher level of expertise to identify and quantify faults as there is no FRA interpretation code widely accepted yet. Currently only magnitude plot is used for detection of the fault using FRA. This work presents an approach of FRA signature interpretation for identifying the location of inter-disk short… CONTINUE READING
