Key Benefits

  • The most flexible protection and control device for distribution feeder applications
  • Advanced IEC61850 Ed. 2 certified implementation, complete settings via SCL files and IEC 61850-9-2 process bus solution enable resource and platform managing optimization and reduce cost of ownership
  • Routable GOOSE (R-GOOSE) enables GOOSE messages going beyond the substation, which enables wide area protection and control applications
  • Unique and secure downed conductor detection
  • Flexible load encroachment allows secure operation during heavy load conditions
  • Advanced automation capabilities
  • Application flexibility with multiple I/O options including high density I/O, programmable logic, modularity, and specific customization
  • Robust network security enabling critical intrastructure protection
  • High-speed inter-relay communications reducing relay-to-relay wiring and costs
  • Phasor Measurement Unit (synchrophasor) according to IEEE® C37.118 (2011) and IEC® 61850-90-5 support
  • 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


  • Primary protection and control for feeders on solidly, impedance, or resonant (Petersen coil) ground systems
  • Busblocking/interlocking schemes
  • Distribution load shedding schemes based on voltage and frequency elements
  • High-speed fault detection for arc flash mitigation
  • Throwover schemes (bus transfer scheme applications)
  • Backup protection for transmission lines, feeders, and transformers
  • Distributed generation (DG) interconnect protection
