Product Code : Alstom_B90
Product Description

The Multilin B90 bus protection relay, a member of the URFamily, features integrated protection and breaker failure for re-configurable MV, HV, EHV multi-section busbars with up to 24 feeders. Use one or more B90 relays together to build a flexible protection system that can be engineered to meet specific application requirements. The B90 performs fast and securelow-impedance bus protection with a sub-cycle tripping time of 0.75 cycles and 06 differential zones per phase.

Key Benefits

  • High-speed protection algorithm for enhanced stability with trip times of 0.75 power cycle
  • Superior CT saturation detector that operates with only 2 msec of saturation-free current for enhanced through-fault stability
  • Suitable for different bus configurations, scalable architecture to protect up to 24 feeders
  • Advanced IEC61850 Ed. 1 and Ed. 2 certified implementation and complete setting in a single SCL file ensures interoper ability, device management 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
  • Use high-speed communications to reduce wiring and installation costs
  • Robust network security enabling Critical Infrastructure Protection through user command logging, and dual permission access control
  • Integrated isolator position monitoring & alarming
  • 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 an nunciator functionality and graphical visualization of phasors
