Abstract
Due to the fault signal containing high and/or slowly decaying dc off-set component, saturation of current transformers cause errors in reproducing secondary current and therefore, secondary current is distorted, which cause relay to maloperate. In this paper, a new method which determines whether current transfomer is saturated is proposed. By designing digital filter of current transfomer, although secondary is distorted, exact secondary current can be reproduced.
