Uszkodzenia eksploatacyjne transformatorów energetycznych
The paper presents main reasons of operating damages of power transformers installed in electric power system. Basing on post-accident test results of the transformers, reasons of operating damages of two groups of transformers are discussed. According to statistic data those transformers show the highest failure rate. It is emphasized that it is necessary to increase the frequency of certain tests in the framework of ongoing control of technical state of the transformer, which in turn will increase its availability in electric power system.
