GE / Alstom B30 Bus Differential System
GE B30 Bus differential relay or the Multilin B30 bus protection relay features integrated protection, control and metering for MV, HV and EHV busbars, providing cost-effective, feature-focused busbar protection. Use the B30 to protect busbars with up to 6 feeders with up to two three-phase differential zones. The Multilin B30 relay is a cost-effective alternative to high-impedance schemes, ideal for breaker-and-half bus schemes, with integrated feeder backup protection and metering.
Cost effective bus protection and metering for up to six feeders with two differential zones. The B30, a member of the UR family, is a digital device that features integrated protection for LV, HV and EHV busbars, providing feature focused busbar and backup protection in a cost effective package.
B30 Bus Differential System Key Benefits
• High speed differential protection algorithm for sub-cycle trip times of 0.75 power cycle
• Advanced IEC 61850 Ed. 1 and Ed. 2 certified implementation, complete settings via SCL files and highly 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
• Superior CT saturation detection with only 2 msec of saturation-free current for enhanced through-fault stability
• Advanced automation capabilities for providing customized protection and control solutions
• Application flexibility with multiple I/O options including high density I/O, programmable logic, modularity, and specific customization
• Robust network security enabling Critical Infrastructure Protection through user command logging, and dual permission access control
• Simplified system integration supporting serial and Ethernet interfaces and multiple protocols
• 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
• Re-configurable simple bus applications, up to 16 feeders and 6 differential zones with breaker failure
• Centralized (six feeders, two zones) or distributed (sixteen feeders, six zones) busbar schemes
• Integrated bus differential, backup protection visualization and metering for LV, MV, HV and EHV substations
