Abstract
The errors introduced by the current transformer (CT) during fault conditions, especially when the CT goes into saturation, affect the accuracy of the protection system. In order to study the transient performance of a CT thoroughly, it is necessary to develop an appropriate numerical CT model. In this paper, a digital model of current transformer suitable for relay studies based on the classical Preisach model is presented
