Abstract
The results of studying the effect of saturation of class P current transformers (CT) in transient modes for actuating the impedance relay of the first stages of remote protection against single-phase short circuits are presented. Various connection configurations of the CT to the resistance relay are examined. Methods of increasing the selectivity and speed of action of the specified protections in the modes under study are substantiated.
