D60 Line Distance Relay

D60 Line Distance Relay

Reduce investments in lifetime costs, engineering, installation and commissioning by using a product with integrated protection, control, automation and monitoring feature in one easy to use package.

A product globally accepted (available in multiple languages) with years of field experience in MV to EHV applications.

What's New in the D60:

  • Fully Compatible with GE Multlilin's HardFiber System - Provides support for GE's IEC 61850 HardFiber Process Bus Solution:
    - Complete IEC61850 Process Bus Solution providing resource optimization and minimizing total P&C lifecycle costs
  • Security Enhancements - Enabling NERC CIP compliance:
    - Dual Permission access requiring live permission from both the user and from SCADA operators before settings can be changed or commands can be given to the relay
    - Logging of user commands in the security audit trail relay - creates a record and sequence of events for troubleshooting and security auditing
  • Ambient Temperature Monitoring:
    - Provides alarms when the ambient temperature exceeds hot extreme

Features and Benefits
  • FlexLogic™ programmable logic
  • Virtual I/O (reduce hardware cost)
  • Expandable I/O
  • Flash memory for field upgrades
  • Optional user programmable pushbuttons
  • User programmable LEDs, fault reports, display messages, and self tests
  • Drawout modules for serviceability
  • Common modules (reduce spare cost)
  • Test mode for I/Os
  • IRIG-B time synchronization and repeater
Applications
  • Protect overhead AC transmission lines of any voltage level; including series compensated lines, with single and three pole tripping.
  • Up to four shots of single/three pole automatic breaker reclosing in breaker-and-a-half or ring bus schemes.
  • Complete support of multiple breaker applications (e.g., Ring Bus, Breaker-and-a-Half).
  • Integrated protection and phasor measurement units.
Protection
  • Full featured transmission line protection system - Five zones ground and phase protection; and five standard pilot aided schemes
  • Enhanced single-pole tripping applications using multi-bit communications schemes
  • Reliable operation on Series Compensated Lines
  • Unique filtering techniques provide better than 5% accuracy even under severe operating conditions and voltage signals fed through CCVT
  • Secure operation during external faults
  • 512 lines of protection logic - build custom protection schemes of your choice
  • Tripping without Logic for direct tripping without the need for configuring Flexlogic Equations
  • Double Point Breaker/Switch Status
Control
  • Easily meet stability requirements - High speed single/three pole tripping and reclosing
  • Dependable - Globally accepted, with performance backed up by many years of field experience
  • Maintenance cost savings and simplification - Modular construction, common hardware, reduced stock of spare parts, plug & play modules
Automation
  • Application flexibility - Multiple I/O options, programmable logic (FlexLogic™), modularity, customize to specific requirements
  • Reduce installation space requirements through compact design - Multifunction device that integrates protection and control functions, programmable pushbuttons and status LEDS, and communication interfaces
Recording & Monitoring
  • Reduce system event analyzing time and cost - Sequence of event reports, Oscillography, data logging, IRIG-B time synchronization
  • Comprehensive metering functionality
  • Synchronized measurement of voltage & current fundamental and sequence component phasors at user programmable streaming rate of 1 to 60 phasors/sec - Integrated PMU and Protection
