The article examines the various transient processes that occur in wide-range current transformers. Secondary transient current values were determined using a mathematical model of a wide range current transformer being studied using different primary current sources. Using the results obtained, the laws of change of secondary currents over time were analyzed. It was found that with increasing angle a of the primary winding of the current transformer under study, the effect of the primary current aperiodic components on the operating mode of the current transformer decreases. It was found that the counter-magnetic driving force created to extend the upper limit of the current change simultaneously reduces the error caused by the aperiodic components of the primary current in the dynamic mode of operation of the current transformer.
