摘要：
The first part of paper deals with the base information about diagnostics of power transformers. The second part of paper deals use of method of frequency domain spectroscopy (FDS) for traction transformer. This method is used in analysis insulating condition and its solution has scientific importance for analysis of power transformer with system of oil-paper. It was found, that the results of these tests are highly impacted by the operating temperature during the experimental measurement. Finally, the paper presents experimental results of this diagnostic measurement for a real traction transformer at different operating temperatures and states (with oil and without). It has been found, that moisture and conductivity between paper and oil in an insulating system are highly dependent from temperature. (C) 2019 The Authors. Published by Elsevier B.V.
