GE Multilin B30 Multiple Sections Low Impedance Busbar Protection

GE Multilin B30 Multiple Sections Low Impedance Busbar Protection

The Multilin B30 bus protection relay features integrated protection, visualization and metering for LV, MV, HV and EHV busbars, providing cost-effective, feature-focused centralized or distributed busbar protection scheme. Use the B30 to protect busbars with up to 6 feeders 2-zones (conventional CT inputs) or up to 16 feeders 6-zones (with process bus module) with up to six 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.

Key Benefits

• High speed differential protection algorithm for sub-cycle trip times of 0.75 power cycle with CT saturation detection with only 2ms of saturation-free current

• Multiple ethernet ports for station and process bus with 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

• Application flexibility with multiple I/O options including high density I/O, programmable logic, modularity, and specific customization

• Advance Cyber security features “CyberSentryTM” that helps meet modern industry requirements

• 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

• Conventional CT/VT or digital S/S via IEC 61850-9-2LE or IEC 61869 process bus

• 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

• CPC schemes - multiple feeders
