For an internal fault, the busbar protection must identify the faulted bus segment, and trip the circuit breakers attached to that bus segment. This requires the busbar protection to use a dynamic bus

Unit busbar protection meets these requirements. Also, in the case busbars sections are separated, only one section needs to be isolated to clear a fault. Busbar protection is actually the strongest when bus
