Grid Solutions Multilin F60 Advanced Protection, Control & Automation for Distribution Feeders The MultilinTM F60 Feeder Protection System provides feeder protection, control, monitoring and metering in an integrated, economical, and compact package. The F60 incorporates a unique and matured algorithm to detect high-impedance faults, such as downed conductor detection. 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 F60 simple to use and configure. Key Benefits • Advanced and flexible protection and control for distribution feeder applications with unique and secure downed conductor detection backed by many years of field experience • Flexible load encroachment allows secure operation during heavy load conditions • Voltage and frequency elements provide load shedding & transfer schemes for increased system uptime and stability • Embedded Synchrophasor measurement capabilities (per IEEE® C37.118), eliminating the need for dedicated PMUs and support for synchrophasor multi-cast (per IEC® 61850-90-5) reducing bandwidth and communications infrastructure costs • 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 • Advanced IEC 61850 Ed. 1 and Ed. 2 certified implementation, complete settings via SCL files and comprehensive process bus support (IEC 61850-9-2LE or 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 • Increased network availability via failover time reduced to zero through IEC® 62439-3 “PRP” support • Supports IEEE C37.111-1999/2013, IEC 60255-24 Ed 2.0 COMTRADE standard Applications • Primary protection and control for feeders on solidly, impedance or resonant (Petersen coil) grounded systems • Busblocking / interlocking schemes • Distribution load shedding schemes based on voltage and frequency elements • High-speed fault detection for arc flash mitigation • Throw over schemes (bus transfer scheme applications) • Backup protection for transmission lines, feeders and transformers • Distributed Generation (DG) interconnect protection , including active and passive anti-islanding Protection & Control • High-impedance fault detection (downed conductor detection) • Thermal overload, incipient cable fault and broken conductor detection • Four-shot autorecloser, VT fuse failure detection, and synchronism check • Protection and control functionality in one box, reducing the number of devices • High density inputs/outputs to support the control of many switchyard assets – all from one powerful device • Integrated large, full color display, for real-time visualization and control of the protected bay Advanced Communications • 3 independent Ethernet ports for simultaneous & dedicated network connections with IEEE 1588 support • IEC 61850-9-2LE/IEC 61869* networked or IEC61850-9-2 Hardfiber process bus support • Direct I/O for secure, high-speed exchange of data between URs for DTT & pilot-aided schemes Cyber Security • CyberSentry™ provides high-end cyber security aligned to industry standards and services (NERC® CIP, AAA, Radius, RBAC, Syslog) Monitoring & Metering • P&M class synchrophasors of voltage, current, and sequence components • Advanced recording capabilities with highcapacity event recorder, configurable and extended waveform capture and data logger •

F60 Feeder Protection System F60 - Protection, Metering, Monitoring and Control As part of the Universal Relay (UR) family, the F60 features high-performance protection, expandable I/O options, integrated monitoring and metering, high-speed communications, and extensive programming and configuration capabilities including: Downed Conductor (Hi-Z) Detection Fires, injuries, and even fatalities may be caused by a live downed conductor. Unfortunately, these high risk incidences often go undetected by conventional protective relays. The Hi-Z element in the F60, unique to Multilin, provides...

F60 Feeder Protection System Auto-Transfer Scheme Implementation Example cause fault current to flow, and therefore the system remains operational, enhancing network reliability. Load Encroachment The load encroachment function in the F60 provides the capability to manage load growth in feeders. The load encroachment element can be set for the feeder’s expected maximum load, reducing the likelihood of false tripping for load conditions while maintaining dependability to trip for legitimate faults. It allows the phase overcurrent elements to be set to see end-of-line phase faults in heavily...

F60 Feeder Protection System detect conditions that would lead to cold load pickup and selectively block protection elements for security during feeder energization. Wattmetric Ground Fault Protection A sensitive wattmetric zero-sequence directional function can be used on isolated or resonant (Petersen coil) grounded, low-resistance grounded and solidly grounded systems to detect ground faults. This function determines the presence and direction of ground faults by measuring the value and direction of zero-sequence power. This flexible element responds to power derived from zero-sequence...
