Multilin UR & URPlus
Proven, State-of-the-Art Protection & Control Systems
The Universal Relay family of protection and control products are built on a common modular platform. All UR products feature high performance protection, expandable I/O, integrated monitoring and metering, high-speed communications, and extensive programming and configuration capabilities. The UR is the basis of simplified power management for the protection of critical assets.
New and Enhanced Communication Capabilities
Cyber Security - CyberSentry UR (FW v7.xx)
CyberSentryTM enables UR devices to deliver full cyber security features that help customers to comply with cyber security requirements (NERC CIP, IEEE 1686, IEC 62443, etc):
Fully Compatible with IEC 61850-9-2LE or IEC61869 process bus schemes:
Extended Oscillography Records (FW v7.xx)
Protection and Control Functionality
Monitoring & Diagnostics
The UR includes high accuracy metering and recording for all AC signals. Voltage, current, and power metering are built into the relay as a standard feature. Current and voltage parameters are available as total RMS magnitude, and as fundamental frequency magnitude and angle.
The UR incorporates advanced automation features including powerful FlexLogic™ programmable logic, communication, and SCADA capabilities that far surpass what is found in the average protection relay. Each UR can be seamlessly integrated with other UR relays for complete system protection and control.
The UR provides advanced communications technologies for remote data and engineering access, making it easy and flexible to use and integrate into new and existing infrastructures. Direct support for fiber optic Ethernet provides high-bandwidth communications allowing for low-latency controls and high-speed file transfers of relay fault and event record information. The available three independent and redundant Ethernet options provide the means to create fault tolerant communication architectures in an easy, cost-effective manner. The UR supports the most popular industry standard protocols enabling easy, direct integration into DCS and SCADA systems.
Interoperability with Embedded IEC 61850
Process Bus System represents a true breakthrough in the installation and ownership of protection and control systems, by reducing the overall labor required for substation design, construction, and testing. This innovative solution addresses the three key issues driving the labor required for protection and control design, construction and testing:
The HardFiber System was designed to address these challenges and reduce the overall labor associated with the tasks of designing, documenting, installing and testing protection and control systems. By specifically targeting copper wiring and all of the labor it requires.UR delivers process bus through the HardFiber System or 61850-9-2LE/61869 process bus module. They allow for greater utilization and optimization of resources with the ultimate goal of reducing the Total Life Cost (TLC) for protection & control. Learn more
The UR connects to GE MU320 or third-party merging units using standard IEC 61869 or IEC 61850-9-2LE communication protocols.
Cyber Secutrity - CyberSentry™ UR (FW v7.4xx)
CyberSentry enables UR devices to deliver full cyber security features that help customers to comply with NERC CIP and NITIR 7628 cyber security requirements through supporting the following core features:
Secure FW upgrade
UR FW files v7.9 and up now include a hash code that allows for authentication prior to being used for upgrading UR devices
Supporting up to 20 alpha- numeric or special characters, UR passwords exceed NERC CIP requirements for password complexity. Individual passwords per role are available.
AAA Server Support (Radius)
Enables integration with centrally managed authentication and accounting of all user activities and uses modern industry best practices and standards that meet and exceed NERC CIP requirements for authentication and password management.
Role Based Access Control (RBAC)
Efficiently administrate users and roles within UR devices. The new and advanced access functions allow users to configure up to five roles for up to eight configurable users with independent passwords. The standard “Remote Authentication Dial In User Service” (Radius) is used for authentication.
Event Recorder (Syslog for SEM)
Capture all cyber security related events within a SOE element (login, logout, invalid password attempts, remote/local access, user in session, settings change, FW update, etc), and then serve and classify data by security level using standard Syslog data format. This enables UR devices integration with established SEM (Security Event Management) systems.
The EnerVista™ suite is an industry-leading set of software programs that simplifies every aspect of using the UR. The EnerVista™ suite provides all the tools to monitor the status of the protected asset, maintain the relay, and integrate information measured by the UR into DCS or SCADA monitoring systems. Convenient COMTRADE and Sequence of Events viewers are an integral part of the UR setup software included with every UR relay, to carry out postmortem event analysis and ensure proper protection system operation.
