GE Multilin D60 – Line Distance Protection System

$1.00

The D60 is suitable for protecting transmission lines and cables including lines equipped with series compensation. The D60 supports dual-breaker applications and can be applied in single-pole or three-pole tripping applications. The D60 is applicable to different teleprotection schemes and includes inter-relay protection communications via direct fiber as well as different interfaces. The D60 also provides synchrophasor measurement over Ethernet per IEEE C37.118.

  • 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
