Product Description
GE Multilin F650‑G‑N‑A‑B‑F‑2‑G‑1‑HI‑C‑E is a high‑performance feeder protection and bay controller IED within GE Vernova F650 series. Adopting dual‑DSP hardware architecture, the “G” variant is equipped with color graphical LCD HMI. It integrates relay protection, metering, local control, fault oscillography and sequence‑of‑event (SOE) recording. It supports FlexLogic programmable logic configuration and comprehensive feeder protection algorithms. With modular plug‑in hardware and multi‑channel I/O, multiple communication ports can operate simultaneously. It supports mainstream power‑system communication protocols for connection with substation SCADA and supervisory systems. Configuration, commissioning and post‑fault analysis are completed via EnerVista software. Built‑in hardware self‑diagnosis and time‑synchronization functions are available. Widely deployed in medium‑voltage power distribution systems, it serves as critical spare‑part protection relay for legacy‑project maintenance and replacementGE Vernova.
