Dissertation on the competition of qualification of research engineer on the specialty 8.05070103 – electrotechnical systems of electricity consumption. – National Technical University of Ukraine «Kyiv Polytechnic Institute», Kyiv, 2016. The structure of high voltage primary measuring channels of current was investigated. Electromagnetic processes of primary measuring channels of current under steady-state and transient conditions of power system were calculated and their spectral analysis using fast Fourier transforms were conducted, demonstrating the generation of noise current transformer secondary substations circle. Keywords: primary measuring chanel of current, current transformer, spectral analisys, mathematical model, saturation.
