GE Multilin UR6DH Universal Relay & Protection Controller with Enhanced Communication for Power Systems
Product Description
The GE Multilin UR6DH is an advanced universal relay and protection controller within GE’s UR Series, optimized for medium/high-voltage power system applications requiring enhanced communication capabilities—including utility substations, industrial power networks, renewable energy plants, and critical infrastructure (data centers, hospitals). Building on the UR6CH platform, the UR6DH features expanded communication interfaces (dual Ethernet, fiber optic ports), enhanced cybersecurity protocols, and support for IEC 61850-9-2LE sampled values, while retaining comprehensive protection logic (overcurrent, voltage, frequency, earth fault) and 0.2% class precision metering. Engineered for high-availability systems, it offers redundant communication paths, dual power inputs, and compliance with IEEE C37.90/IEC 61850 standards, ensuring reliable fault detection, real-time monitoring, and secure integration with modern SCADA/EMS systems.
Key Functions
The UR6DH universal relay delivers enhanced protection, metering, and secure communication for power distribution systems. Key functions include: Full suite of protection logic (overcurrent/instantaneous overcurrent, under/over voltage, frequency protection 45-65 Hz, phase imbalance, earth fault, negative sequence protection); 0.2% class precision metering (V, I, kW, kVAR, kWh, power factor, THD) with 256 samples/cycle sampling rate; enhanced communication (dual 10/100/1000 Mbps Ethernet ports, fiber optic ports, IEC 61850 GOOSE/MMS/sampled values, Modbus TCP/RTU, DNP3.0); built-in cybersecurity (role-based access control, TLS 1.3, secure boot) for compliance with NERC CIP standards; 12 configurable digital inputs (24 VDC) and 10 Form C relay outputs (5 A @ 250 VAC/30 VDC) for advanced interlocking; event recording (2000 time-stamped events) and fault waveform capture (20 cycles pre/post fault) for detailed post-fault analysis; dual redundant power inputs (85-265 VAC/100-300 VDC) for high availability; and galvanic isolation (2500 VAC) between input/output circuits and control logic.
Application Scenarios
The GE Multilin UR6DH universal relay is deployed in mission-critical power systems requiring enhanced communication and cybersecurity. In utility transmission/distribution substations, it provides protection for transformers, feeders, and capacitor banks with secure, high-speed data transmission to SCADA/EMS via IEC 61850 sampled values. For large industrial plants (steel, chemical, oil & gas), it protects medium-voltage switchgear, motor control centers, and backup generator systems, with redundant communication paths to prevent data loss. In renewable energy installations (utility-scale solar/wind farms), it integrates with grid-tie inverters and battery storage systems to monitor grid parameters, provide anti-islanding protection, and comply with grid code requirements. The relay is also ideal for critical infrastructure (data centers, hospitals, railway electrification) where secure, uninterrupted power system monitoring and protection are essential for operational continuity.
