Abstract: Described herein are adaptable control apparatus indicators for dedicated operations of a device for operating an electric power delivery system. The control apparatus indicators may be buttons on an intelligent electronic device (IED) used for the dedicated operations of opening and closing a circuit breaker of the electric power delivery system. The colors of the control apparatus indicators may be configurable by a user upon configuration of the IED.

Abstract: The presently described systems and methods include differential protection architectures for power lines, including three-phase transmission lines and distribution lines, in which each protective device monitors and protects more than one power line. A protective device with multi-channel line current differential protection provides additional security from data corruption and/or single event upsets. A protective device on one end of a transmission line may include multiple communication channels to simultaneously receive independent differential data (e.g., current measurements) from protective devices on the other end of the transmission line. The device may use the independent channels of line current differential protection data to implement multiple independent differential protection functions for two or more power line segments.
