It provides improved calculation of corrections and increase accuracy of measuring of the phase voltages. The proposed method of approximation of magnetization characteristics of the current transformer magnetic core based on the Floater-Hormann algorithm has been adapted by the authors for modeling the problems of current transformers for the calculation of corrections. The effect of asymmetry of input signals on loadings and errors of current transformers has been studied. Importance of the permanent automatic measuring of the second loadings of current transformers has been proved. The methods, algorithms and programs of preparation of input information for the correction of errors of the measuring channels of current and voltage phasors of the monitoring systems on the basis of "Regina-Ch" has been developed. Their use increases accuracy of measuring of phasor parameters of the electrical power systems mode and efficiency of system management.
