GE Multilin UR series

GE Multilin UR series
The general relay series of protection and control products are built on a general modular platform. All UR products feature high-performance protection, scalable I/O, integrated monitoring and metering, high-speed communication, as well as extensive programming and configuration capabilities. UR is the foundation of simplified power management for protecting critical assets.

Main advantages
A modular structure is achieved through universal hardware, reduced spare parts and plug-and-play modules to save costs and simplify expenses
CyberSentry UR provides powerful cybersecurity that complies with industry standards and services
Application flexibility with multiple I/O options, including high-density I/O, programmable logic, modularization and specific customization
Advanced IEC 61850 1st and 2nd edition certification implementation, complete setup through SCL documents and comprehensive process bus support (IEC 61850-9-2LE, IEC 61869 or IEC 61850-9-2 hard Fiber) ensure interoperability, optimize equipment management and reduce ownership costs
Routable GOOSE (R-GOOSE) enables GOOSE messages to go beyond substations, thereby achieving wide-area protection and control applications
The integrated large full-color display screen provides real-time visualization and control of the protected bracket through bracket simulation and graphical visualization of the signaler function and phasor
Three Ethernet ports support specific-purpose LAN support, reducing latency caused by large amounts of traffic in critical communications
The phasor measurement unit (synchronous phasor) complies with IEEE C37.118 (2014) and IEC 61850-90-5 and streams directly from your protective equipment
“Application

Synchronous phasor functions in generator, transformer, line distance, line differential and feeder applications
Multiple configurable PMU components (up to 6 for selected products)
Expansion display wave – Capture the expansion event of 64 samples per cycle
Event logger – 1024 time-marked events, with a 0.5ms digital input scan
Data logger – up to 16 channels, and users can select the sampling rate
Fault locator and user-programmable fault reporting
Circuit breaker condition monitoring, including circuit breaker arc current (I2t)
Measurement – current, voltage, power, power factor, frequency
The temperature of the broken rotor rod and the motor is detected through RTD input
Monitoring and diagnosis
UR encompasses high-precision measurement and recording of all AC signals. Voltage, current and power measurement are built into the relay as standard functions. The current and voltage parameters can be provided as the total RMS amplitude as well as the fundamental frequency amplitude and Angle.
