IEC 61850 Process Bus Interface

• Robust communications with up to 8 HardFiber Bricks

• Redundant architecture for dependability and security

Monitoring and Metering

• Synchrophasors in select products with IEEE C37.118 (2011) and

IEC 61850-90-5 support

• Advanced recording capabilities deliver a 1024 event recorder,

configurable and extended waveform capture and data logger

• Fault locator and user-programmable fault reports

• Breaker condition monitoring including breaker arcing current

(I2t), breaker re-strike and breaker flashover

• Metering: current, voltage, power, power factor, frequency,

voltage & current harmonics, energy, demand, phasors, etc.

EnerVista™ Software

• Graphical Logic Designer and Logic Monitor to simplify

configuration and testing procedures via EnerVista UR Engineer

• Service and update notification toolset ensures device documents

and software are up-to-date via EnerVista Launchpad

• EnerVista Integrator providing easy integration of data in the UR

Family into new or existing monitoring and control systems

FEATURES

Protection and Control

• Fast and segregated line current differential and distance

protection functionality in a single device

• Phase segregated line current differential with adaptive restraint

and ground differential, stub bus protection

• Phase distance (five zones) with independent settings for compensation

• Single-pole tripping, breaker-and-half with independent current

source support

• Complete generator protection with 100% stator ground fault

detection with sub-harmonic injection and field ground protection

Communications

• Networking interfaces: 10 or 100MB copper or fiber optic

Ethernet, RS485, RS232, RS422, G.703, C37.94, up to three

independent ethernet ports

• Multiple protocols: IEC 61850, DNP 3.0 and Modbus® serial/TCP,

IEEE 1588, IEC 60870-5-104 and 103, PRP, SNTP, HTTP, TFTP, EGD

• Direct I/O: secure, high-speed exchange of data between URs for

direct transfer trip and I/O extension applications

• 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

APPLICATIONS

• Protection, control, monitoring and supervision of power assets

across generation, transmission, distribution, substation and

industrial systems

• Utility substation and industrial plant automation

• Digital fault recording and Sequence of Event (SOE) recording

• Predictive maintenance through data analysis and trending

• Synchrophasor based monitoring and control systems with

specialized PMU devices that support multiple feeders

• Complex protection & control and wide area monitoring solutions

with complete diagnostic and automation capabilities (URPlus)

KEY 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
