GE Multilin™ UR & URPlus Proven, State-of-the-Art Protection & Control Systems

GE Multilin™ UR & URPlus Proven, State-of-the-Art Protection  & Control Systems 

Overview 

The Universal Relay (UR) is a family of leading edge protection and control products built on a common modular platform. All UR products feature high-performance protection, expandable I/O options, integrated monitoring and metering, high-speed communications, and extensive programming and configuration capabilities. The UR forms the basis of simplified power management for the protection of critical assets, either as a stand-alone device or within an overall power automation system. The UR is managed and programmed through EnerVista Launchpad. This powerful software package, which is included with each relay, not only allows the setpoints of the relay to be programmed, but also provides the capability to manage setpoint files, automatically access the latest versions of firmware/ documentation and provide a window into the substation automation system.

G60 Medium to Large Generators 

The G60 provides comprehensive primary and backup protection for medium and large generators, including large steam and combustion turbines, combined-cycle generators and multicircuit hydro units. The G60 includes advanced automation and communication capabilities, extensive I/O options, and powerful fault recording features that simplify postmortem analysis and minimize generator downtime.

G30 Combined Generator & Transformer Protection 

The G30 is a flexible system that can be used on small and medium generators, generator and step-up transformer arrangements or backup protection of large generators. Similar to the G60, the G30 also offers comprehensive protection and monitoring elements.

BENEFITS

• Modular construction: common hardware, reduced stock of spare parts, plug & play modules for maintenance cost savings and simplification 

• Proven flexibility and customization capabilities make UR/URPlus devices suitable to retrofit almost any kind of legacy P&C scheme 

• Large HMI and annunciator panels provide local monitoring & control capabilities, and backup the substation HMI 

• Phasor Measurement Unit (synchrophasor) according to IIEEE® C37.118 (2011) and IEC® 61850-90-5 directly streamed from your protective device 

• Three ethernet ports enable purpose specific LAN support that eliminates latency effect of heavy traffic protocols on mission critical communication services

• Embedded IEEE 1588 time synchronization protocol support eliminates dedicated IRIG-B wiring requirements for P&C devices 

• Complete IEC 61850 Process Bus solution provides resource optimization and minimizes total P&C life cycle costs 

• Increase network availability by reducing failover time to zero through IEC 62439-3 “PRP” support 

• CyberSentry™ provides high-end cyber security aligned to industry standards and services (NERC® CIP, based, AAA, Radius, RBAC, Syslog) 

• Enhanced CT/VT module diagnostics verify analog signal integrity using an advanced algorithm, ensuring reliability 

• Reduces system event analysis effort with the support of embedded high-end and extended recording functionality

FEATURES

Protection and Control
