F650-B-F-G-F-2-G-1-HI-E
The GE MULTLIN F650-B-F-G-F2-G-1-HI-E combines cutting-edge technology with rugged industrial design. Its high-speed fault detection (≤10 ms) ensures rapid isolation of faulty sections, critical for preventing cascading failures in power grids. The relay’s dual-stage current limiting and overvoltage protection safeguard connected equipment from transient spikes, while its advanced metering capabilities provide real-time insights into power quality, including voltage, current, and energy consumption.
The
GE MULTLIN F650-B-F-G-F2-G-1-HI-E excels in environments where power reliability is non-negotiable. In utility substations, it protects transmission lines and distribution feeders, coordinating with circuit breakers to isolate faults and restore power within seconds. For example, in a smart grid, the relay’s load shedding capabilities adjust power distribution during peak demand, preventing blackouts and ensuring grid stability. Its synchrocheck function also enables safe reconnection of distributed energy resources (DERs) like solar farms, supporting the transition to renewable energy.
