Abstract
This paper deals with power oil transformer 40 MVA complex diagnostics and its state evaluation. The diagnostic methods like the evaluation of capacitances, loss factor tg δ and analysis of frequency responses by SFRA method were used for identification. These diagnostic methods enable identification of fault by comparative measurements. In this paper is shows identification of short circuit by use of interwinding SFRA measurements.
