The GE Micom P54A Relay is designed for overhead line and cable applications up to 6 terminals, interfacing readily with the longitudinal (end-to-end) communications channel between line terminals. Previously, transmission and distribution circuits would have two or three ends only, whereas five or more ends are becoming common to connect renewable generation. All models are ready for protection topologies ranging from two to six terminals, whether those multi-terminals exist now, or are provisioned for connection in the future. Multi-ended current differential protection uses a high-speed and innovative biased differential characteristic. Phase-segregated differential elements provide consistent detection of solid and resistive faults.
