In the electric power industry, oil-type power transformers are considered the main device that ensures reliable transmission of electric power, and their technical capabilities are analyzed. Factors affecting long-term reliable operation of oil-fired power transformers are investigated. In this paper, a simulation model is developed to assess the condition of oil power transformers during rapid diagnosis. A mathematical model has also been developed that allows calculating the absorption coefficients and the general technical condition of oil power transformers depending on the value of the input variables of oil power transformers operating in city power networks. The authors developed a Simulink model for rapid assessment of the technical condition of the oil power transformer. A block diagram is created that allows to determine the value of the technical condition of the oil power transformer according to the vibroacoustic parameters.
