Description


High-speed transmission line protection with flexibility for three or single pole tripping. The D60, a member of the UR Family of protection relays, is a numerical line distance protection system, which provides protection for medium to extra high voltage transmission lines and an integrated system providing control, automation, metering, synchro phasors, monitoring and communications in one easy to use package. Use the D60 on applications requiring fast single or three phase tripping, single or three pole re-closing, series compensated lines, with multiple breakers per terminal. Distance protection has been tuned to meet the rigorous application requirements of IEC-driven end-users.

Key benefits:

  • Five zone quad or mho, phase and ground distance protection
  • Advanced IEC 61850 Ed. 1 and Ed. 2 certified implementation, complete settings via SCL files and flexible process bus support (IEC 61850-9-2LE or IEC 61850-9-2 Hardfiber) ensures interoperability, device managing optimization and reduced cost of ownership
  • Routable GOOSE (R-GOOSE) enables GOOSE messages going beyond the substation, which enables wide area protection and control applications
  • Reliable and secure protection on series-compensated lines
  • Superior phase selection algorithm
  • Supports multiple standard pilot schemes
  • Flexible programmable logic for building customized schemes
  • Simplified teleprotection interfaces with direct I/O communications
  • Robust network security enabling Critical Infrastructure Protection
  • Phasor Measurement Unit (synchrophasor) according to IEEE® C37.118 (2011) and IEC® 61850-90-5 support
  • Application flexibility with multiple I/O options including high density I/O, programmable logic, modularity, and specific customization
  • An integrated large, full color display, provides real-time visualization and control of the protected bay, via a bay mimic as well as annunciator functionality and graphical visualization of phasors

Cyber Security – 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:

  • Password Complexity

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.

  • EnerVista™ Software

The EnerVista™ suite is an industry-leading set of software programs that simplifies every aspect of using the D60 relay. The EnerVista™ suite provides all the tools to monitor the status of the protected asset, maintain the relay, and integrate information measured by the D60 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.
