F35N03HUH8LH6AM6EW7C  Multilin F35 Feeder Protection System

The F35, 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.

Key Benefits

• Advanced IEC 61850 Ed. 1 and Ed. 2 certified implementation, complete settings via SCL files and flexible
• process bus support (IEC 61850-9-2LE, IEC 61869 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
• Advance Cyber security features “CyberSentryTM” that helps meet modern industry requirements
• Simplified system integration with communications supporting serial and Ethernet interfaces and multiple protocols
• 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

F35N03HUH8LH6AM6EW7C

The MultilinTM F35 feeder protection system provides feeder protection, control, monitoring and metering
in an integrated, economical, and compact package. As part of the Universal Relay (UR) Family, the F35
provides cost-effective solutions and features high-performance protection, expandable I/O options,
integrated monitoring and metering, high-speed communications, and extensive programming and
configuration capabilities.
The F35 can be configured to protect up to six feeders or protect up to five feeders when bus voltage
measurement is required. It also provides fast and deterministic execution of programmable logic, which
is necessary for substation automation applications. Graphical programming tools (Viewpoint Engineer),
supported by a library of logic components, make the F35 simple to use and configure.
