Abstract \u2013 The depletion of explored reserves of fossil fuels leads to an increase in their value and compels humanity to seek new and alternative forms of energy. Rapid growth of photovoltaic, wind, small hydro power plants, etc. led to the redistribution of electricity flows along transmission lines through high-voltage power transformers, whose passport resource has already been exhausted. The risk of accidents and power shortages is increasing. Therefore, it is necessary to investigate the damage of high-voltage equipment of power plants using renewable energy to improve the known and to develop new methods and means of monitoring the technical condition of such equipment. Therefore, the analysis of damage to the power transformer at the photovoltaic power plant, tasks and research results are relevant. The presented results of the analysis of the damaged and newly investigated transformers indicate that the operating conditions of these transformers were not violated. The proposed circuits, connection points, research methodology, and FRAnalyzer devices from Omicron, FLUKE 1736 and SATEC PM 175 allow you to quickly and qualitatively determine the technical state of the electric power and the quality of electricity. The analysis of the measured frequency response of the investigated CT indicates the proper condition of the investigated CT, namely because: the deviation of the received frequency response is observed within 2%, it indicates that the CT is free of damage; on some characteristics and on the corresponding frequency ranges, deviations were observed within 5%.
