In the paper is presented experimental analysis and diagnostics of insulating system oil-paper for power transformers. In the first part of the paper is described base theory about measurement and diagnostics insulating part (oil and paper) of transformers. In the other two parts of the paper is presented experimental results of the diagnostic measurement for the transformer 22/0.4 kV at constant temperature. Specifically, in the second part is described measuring time method of insulating diagnostics - return voltage measurement (RVM). This method is used for analysis of condition of paper moisture of high-voltage equipment. In the third part is described measuring method of insulating frequency diagnostics - frequency domain spectroscopy (FDS). This method is used for analysis insulating condition of high-voltage equipment with insulating oil-paper. The both measuring methods are unique in terms of analysis of insulating system of oil power transformers. In comparison with other methods, the RVM and FDS methods it is possible comparison and evaluate the moisture state of the dielectric paper of the power transformer with high reliability and accurate. Their reliability in determining moisture in paper was shown by determining the same result (3.5%) on the same measured transformer.
