Summary:The paper deals with the identification of the breakdown of the transformer withdrawn from operation because of repeated reaction of transformer protections. Successively the transformer was put of operation, removed from the distribution and put to diagnostic measmements. For identification of the failure were used diagnostic methods, e.g. Sweep Frequency Response Analysis (according to IEC 60076-18), measurement of winding resistances, measmement of isolation resistances and capacitances. The results were compared with reference measmements. [PUBLICATION ABSTRACT]
