Electromagnetic Transient of Current Transformer and Its Digital Simulation

Qi Weiguo  
Based on experiments, this paper describes the electromagneti cper-formances of different types of CT cores under various operating conditions by means of B-H curves.This paper also introduces the digital simulation of electromagnetic transient processes of CT iron core and their computation programs. The unbalanced current and, the stability of the differential protection during an external fault are analyzed by the above computation method.
