description: This work is devoted to experimental determination of parameters of current transformers, which are used for their simulation in steady-state and transient pro-cesses. The tasks that were solved during the research: 1. Experimental derivation of CT substitution parameters for the linear mod-el. 2. Experimental obtaining of the I-V curves for the method of equivalent si-nusoids. 3. Obtaining the curve of 10% CT error for the method of calculation by rec-tangular approximation of the magnetization characteristic. 4. Experimental obtaining of the initial magnetization curve and the family of symmetrical magnetization loops of CTs for models using experimentally taken magnetization characteristics of CTs. 5. Experimental acquisition of CT magnetization transients to verify the models. To carry out the experiments we wrote a program in a LabVIEW programming en-vironment, which allowed us to automatically calculate the magnetic induction and magnetic field strength, approximate the measured data, build oscillograms of cur-rents and the magnetization process in coordinates B(H). The programs responsible for digital signal generation and its recording were also written. As a result, all nec-essary parameters for using the most well-known CT models were obtained.
