GE BSP10 369B1879G5001 – High-Speed Busbar Protection Relay | GE Multilin Series
Engineering Background: The GE BSP10 (Part No. 369B1879G5001) is a dedicated busbar differential protection relay developed by GE’s Multilin division for high-voltage and medium-voltage substation applications. Designed to detect and isolate internal busbar faults within milliseconds, it is a critical component in modern power system protection architectures where fault clearance speed directly impacts equipment integrity and grid stability.
Product Positioning: The BSP10 targets utility-grade and industrial substation engineers who require IEC-compliant, high-speed differential protection with deterministic trip times. It is engineered for new installations and retrofit projects in transmission substations, distribution switchgear, and industrial power plants where busbar faults pose the highest risk to system continuity.

- Proven Field Reliability: GE Multilin relays are deployed in thousands of substations globally with documented MTBF exceeding industry benchmarks.
System Architecture & Signal Flow
The BSP10 collects current signals from all feeder CTs connected to the protected busbar zone. The relay continuously computes the differential current (sum of all feeder currents). Under normal load conditions, the differential current remains near zero. Upon detection of an internal fault, the differential current exceeds the relay’s pickup threshold, triggering instantaneous trip commands to all associated circuit breakers via hardwired output contacts or IEC 61850 GOOSE messages. CT supervision algorithms run in parallel to validate CT circuit integrity and block spurious trips caused by CT failures.
