GE Multilin UR6CH Universal Relay & Protection Controller for Power Systems
Product Description
The GE Multilin UR6CH is a versatile, high-performance universal relay and protection controller designed for medium and high-voltage power system applications, including distribution substations, industrial power networks, and renewable energy installations. As part of GE's UR Series, this multi-function relay integrates overcurrent, undervoltage, overvoltage, frequency, and phase imbalance protection logic, combined with advanced metering, monitoring, and communication capabilities. Featuring a modular hardware design, configurable protection schemes, and compliance with IEEE C37.90 and IEC 61850 standards, the UR6CH delivers reliable fault detection and isolation, real-time power system monitoring, and seamless integration with SCADA/EMS systems in harsh industrial environments.
Key Functions
The UR6CH universal relay delivers comprehensive protection and control for power distribution systems. Key functions include: Multi-function protection logic (overcurrent/instantaneous overcurrent, under/over voltage, frequency protection, phase imbalance, earth fault detection); advanced power metering (V, I, kW, kVAR, kWh, power factor, THD) with 0.2% accuracy class; configurable protection settings (time-delay curves, pickup values, reset characteristics) via front-panel HMI or GE EnerVista software; built-in communication interfaces (Ethernet, RS-485, IEC 61850 GOOSE/MMS) for SCADA integration; 8 configurable digital inputs (24 VDC) and 8 Form C relay outputs for interlocking/control; event recording (1000 events) and fault waveform capture (10 cycles) for post-fault analysis; and self-diagnostics with LED status indicators for health monitoring. The relay also features galvanic isolation (2500 VAC) between input/output circuits and control logic.
Application Scenarios
The GE Multilin UR6CH universal relay is deployed in medium/high-voltage power distribution systems across utility, industrial, and renewable energy sectors. In utility substations, it provides overcurrent and voltage protection for distribution transformers, feeders, and capacitor banks, with remote monitoring via SCADA. For industrial plants (manufacturing, mining, oil & gas), it protects motor control centers, switchgear, and backup generator systems from electrical faults, ensuring uninterrupted power to critical processes. In renewable energy installations (solar/wind farms), it integrates with grid-tie inverters and battery storage systems to monitor grid parameters and provide anti-islanding protection. The relay is also suitable for commercial buildings (data centers, hospitals) and railway electrification systems—all scenarios requiring flexible, reliable power system protection and monitoring.
