Description

GE / Alstom Multilin F35 Feeder Protection Relay

The GE F35 Feeder Relay, a member of the UR Family of protection relays, provides cost-effective feeder protection, control and metering for up to five feeders with busbar voltage measurement, or six feeders without busbar voltage in one integrated package. Use the F35 as a stand-alone device or as a component of an automated substation control system.

GE F35 Feeder Relay Key Benefits

• Cost-effective and flexible protection and control device for distribution feeder applications
• Advanced IEC 61850 Ed. 1 and Ed. 2 certified implementation, complete settings via SCL files and flexible process bus support (IEC 61850-9-2LE or IEC 61850-9-2 Hardfiber) ensures interoperability, device managing optimization and reduced cost of ownership
• Routable GOOSE (R-GOOSE) enables GOOSE messages going beyond the substation, which enables wide area protection and control applications
• High-end fault and disturbance recording, including internal relay operating signals
• Robust network security enabling Critical Infrastructure Protection through user command logging, and dual permission access control
• Simplified system integration with communications supporting serial and Ethernet interfaces and multiple protocols
• Reduced relay-to-relay wiring and associated installation costs through high-speed inter-relay communications
• Supports latest edition of waveform capture (COMTRADE 2013) simplifying fault records management
• Application flexibility with multiple I/O options including high density I/O, programmable logic, modularity, and specific customization
• An integrated large, full color display, provides real-time visualization and control of the protected bay, via a bay mimic as well as annunciator functionality and graphical visualization of phasors

Applications
• Primary protection and control for multiple distribution feeders
• Distribution load shedding schemes based on voltage and frequency elements
• Busblocking/interlocking schemes
• Throwover schemes (bus transfer scheme applications)
• Distributed generation (DG) interconnect protection, including active and passive anti-islanding
