Abstract
Some recent developments in the protection of electric power systems to meet the special problems on the system of the Southern California Edison Company, Ltd., are discussed in this paper. Among these developments are means to provide greater protection against high resistance faults, a simplified carrier current pilot protection scheme, a method of automatic system separation when out-of-step conditions occur, and several miscellaneous applications.Keywords
