The UR7HH is an advanced communication module developed by GE Grid Solutions (Multilin) for the UR Series universal relay platform. Installed into the relay chassis backplane, the UR7HH acts as the primary networking gateway, bridging the host relay to supervisory control systems via fiber and Ethernet. The UR7HH supports dual independent communication channels for redundancy and features three Ethernet ports, multimode fiber interfaces, and full IEC 61850 Ed. 1 & 2 protocol support. With IEEE 1588 time synchronization, PRP redundancy, and a rugged –40°C to +70°C temperature range, the UR7HH ensures reliable inter‑relay data exchange and substation automation even in harsh electrical environments.
Generator protection and control systems (G60) requiring high‑speed relay‑to‑SCADA communications
Transformer protection (T60/T35) with redundant fiber network architectures
Line current differential protection (L90/L30) over multimode fiber links
Feeder protection (F60/F35) integrated into IEC 61850‑based substation automation systems
Busbar differential protection (B90/B30) with parallel redundancy protocol (PRP)
Motor protection systems (M60) requiring real‑time GOOSE messaging and peer‑to‑peer logic coordination
Capacitor bank protection (C70) and breaker controller (C60/C30) for utility substations
Wide‑area monitoring and control systems (WAMS/WAPC) using R‑GOOSE beyond the substation
Dual‑Channel Fiber Communication: Equipped with two 820nm multimode ST fiber ports supporting distances up to 2 km, providing noise‑immune, electrically isolated inter‑relay data transfer.
Three Independent Ethernet Ports: Allows segregation of heavy traffic (e.g., synchrophasors) from mission‑critical services (GOOSE, MMS) to eliminate potential latency effects.
Comprehensive Protocol Support: Fully certified for IEC 61850 Editions 1 and 2 (GOOSE, MMS, Sampled Values), plus DNP3, Modbus TCP/RTU, IEC 60870‑5‑104, and IEEE C37.118 synchrophasors.
IEEE 1588 Precision Time Protocol (PTP): Eliminates dedicated IRIG‑B wiring by providing sub‑microsecond time synchronization directly over the Ethernet network.
Zero‑Downtime Redundancy: Supports PRP (Parallel Redundancy Protocol, IEC 62439‑3) and HSR, enabling seamless failover without interruption to communication services.
Routable GOOSE (R‑GOOSE): Extends GOOSE messaging beyond the substation for wide‑area protection and control applications (WAPC).
Hot‑Swappable: Supports live insertion and removal for in‑service maintenance without powering down the relay chassis.
Galvanic Isolation: 2500 Vrms isolation between fiber circuits and backplane blocks ground potential differences and surge transients in high‑voltage environments.
Dual Power and Network Redundancy: Dual power input and dual network hot‑standby ensure continuous operation even if one power source or network path fails.
Comprehensive Cybersecurity: Embedded CyberSentry™ suite with Role‑Based Access Control (RBAC), AAA (Radius) server support, Syslog event recording, and SNMPv3.
Provides high‑speed communication between UR series relays and SCADA/DCS/HMI systems over Ethernet or fiber optical networks.
Enables peer‑to‑peer GOOSE messaging between up to 16 remote UR devices for distributed protection schemes (e.g., breaker failure, transfer tripping, interlocking).
Converts internal UR protection and metering data into industry‑standard protocols (IEC 61850, DNP3, Modbus) for seamless integration with third‑party control systems.
Synchronizes multiple UR relays within a substation using IEEE 1588 PTP over Ethernet, eliminating separate timing wiring and improving event time‑stamp accuracy to ±1 μs.
Manages network redundancy via PRP and HSR, duplicating data packets across two independent networks so one data packet always reaches the receiving device with no time delay.
Transmits synchrophasor (PMU) data streams conforming to IEEE C37.118 and IEC 61850‑90‑5 directly from the protective relay to phasor data concentrators (PDCs).
Supports Routable GOOSE (R‑GOOSE) to extend substation LAN messaging across wide‑area networks for advanced protection schemes.
Provides onboard diagnostics tracking optical power levels, link health, transceiver fault status, and self‑test results for proactive maintenance.
Hosts an integrated color graphical display (CPU‑mounted variant) for local visualization of phasor diagrams, event summaries, and protection logic status without external tools.
