GE Multilin UR-8LV UR 8LV - CT/VT Module

Universal Relay (UR) Family Overview

The Universal Relay (UR) family of protection and control products is built on a common modular platform. All UR devices deliver high-performance protection, expandable I/O, integrated monitoring and metering, high-speed communications, and extensive programming and configuration capabilities. The UR series simplifies power management to protect critical assets efficiently.

Key Benefits

• Modular Construction:
  Common hardware platform with plug-and-play modules reduces spare parts inventory, lowers costs, and simplifies maintenance.

• Cybersecurity:
  CyberSentry UR provides robust network security aligned with industry standards and services.

• Application Flexibility:
  Multiple I/O options including high-density I/O, programmable logic, modularity, and customization for specific applications.

• Advanced IEC 61850 Certification:
  Certified to Edition 1 and Edition 2 standards. Supports complete settings via SCL files and comprehensive process bus compatibility (IEC 61850-9-2LE, IEC 61869, IEC 61850-9-2 Hardfiber), ensuring interoperability, optimized device management, and reduced ownership costs.

• Routable GOOSE (R-GOOSE):
  Enables GOOSE messaging beyond the substation, supporting wide-area protection and control applications.

• Integrated Full-Color Display:
  Large display provides real-time visualization and control of the protected bay, including bay mimic, annunciator functionality, and graphical phasor visualization.

• Multiple Ethernet Ports:
  Three Ethernet ports provide dedicated LAN support, reducing latency caused by heavy traffic on critical communication channels.

• Phasor Measurement Unit (PMU):
  IEEE C37.118 (2014) and IEC 61850-90-5 compliant synchrophasor measurements, directly streamed from the protective device.

Applications

• Protection and control of generators, transformers, transmission lines (distance, line differential, and phase comparison), distribution networks, capacitor banks, motor protection, and controllers.

• Utility substations and industrial plant automation.

• Digital fault recording and sequence of event recording.

• Predictive maintenance via data analysis and trending.

• Advanced protection, control, and automation schemes.

• New graphical front panel with expanded bay controller and automation capabilities.

• Complex protection and control solutions for CPC (Centralized Protection and Control) schemes involving multiple feeders.
