Abstract

One of the most important failure issues in transformers is the turn-To-Turn short circuit fault. Turn-Toturn fault can be occurred due to the inter-Turn paper insulation deterioration, or due to removing thin layer coated insulation between the winding turns. To date, there is no specific pre-determined method to find (or at least suspect) a deteriorated turn-To-Turn insulation medium before catastrophic failure. Frequency Response Analysis (FRA) as a method introduced for transformer mechanical defect recognition, may be able to recognize the turn-To-Turn fault potential and assist on this case. Hence, this study has concentrated practically on FRA capability to find turn-Toturn insulation degradation as well as inter-Turn aging rate. To this end, two different test objects are used and FRA signatures in various conditions are recorded. FRA results are provided and technically discussed.
