Summary: The article analyzes existing methods of diagnosing power transformers (PTs). The technique of experiment planning using D-optimal plans is investigated. According to the results of the study, a D-optimal plan of the frequency response measurements was created, which defines the algorithm of the studies. On the example of PT type TMG 1000/10 it is determined that 13 measurements are required to evaluate the condition of the PT during the interpretation of the results of the frequency response measurements. The method of determining the average frequency characteristic of PT is given. This amplitude-frequency characteristic can be used to check the PT status and to detect damage at an early stage of their development.
