A Current Transformer Saturation Detection Algorithm for Use in Current Differential Protection

Abstract

A current transformer (CT) saturation detection algorithm for use in current differential protection is described. The algorithm evaluates the start and end of each CT saturation period using the "largest modulus series"; this is derived from the third order difference function applied to the secondary current. To reduce the possibility of false detection… (More)
