Coordination and protection of busbar distribution
System performance is guaranteed by standardization of circuit breaker protection and BBT busbar distribution. The performance of a busbar distribution system depends on the specific characteristics

BUSBAR PROTECTION
The calculated current results in disconnection of the faulty busbar by the busbar differential protection. In the case of current transformers arranged on the line side, the fault must be disconnected by the
Busbar Differential Protection Scheme
In current differential protection of busbar, if CT secondary circuits, or bus wires is open the relay may be operated to isolate the bus from live system. But this is not desirable.
Bus Protection Theory
A fault between the circuit breaker and the CT is in a blind spot of the bus protection. To clear the fault the busbar must be tripped, but the differential zone will not see this fault.
