Product Description

Multilin D30 Line Distance Protection System

The D30 is a cost-effective distance protection systemsuitable for primary protection of sub-transmission lines and as a backupprotection for HV, EHV lines, reactors and generators. The D30 provides five zonesof phase and ground distance protection along with complete overcurrent andvoltage protection functions intended for three-pole tripping applications. TheD30 comes with versatile automation features using custom pilot schemes, whichcan be built.

Key Benefits

  • Cost effective, 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
  • Programmable logic for building customized pilot schemes
  • Reduced relay-to-relay wiring and associated installation costs
  • Simplified teleprotection interfaces with direct I/O communications hardware
  • Robust network security enabling Critical Infrastructure Protection
  • Application flexibility
  • Ambient temperature monitoring
  • 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

Applications

  • Overhead sub-transmission lines and underground cables including series-compensated lines
  • Circuits requiring three-pole autoreclosing and independent synchrocheck supervision
  • Circuits with in-zone power transformers
  • Secure application with Capacitively-Coupled Voltage Transformers (CCVTs)
  • Backup protection for generators, transformers and reactors
