The study of transient processes taking place in current transformers

Abstract

AbstractThe article examines the transients that occur in current transformers and determines the magnetizing current values in the operator method using the primary current source. Using the results obtained, the laws of change of magnetic currents over time were analyzed. A comparative analysis of the laws of change of magnetic current aperiodic components over time for closed and non-closed core current transformers under study was performed. It has been found that closed-core current transformers can be used in slow-circuit protection circuits, as an alternating current source, and in other cases when an efficient transfer of power from the primary winding to the secondary winding is required.
