Busbar Protection Differential Connection
Busbar protection relay works on the differential principle i. comparing the currents entering and leaving a protected busbar section. Current Differential Protection: This protection method connects CT secondaries in parallel and. Busbar protection (BBP): Protection intended to detect and operate to clear faults on a busbar. Busbars in power systems are the location where transmission lines, generation sources, and distribution loads converge. Because of this convergence, short circuits located on or near the busbar tend to have very high magnitude currents. The high magnitude fault currents require high-speed. When the fault occurs on the bus bars whole of the supply is interrupted, and all the healthy feeders are disconnected. A busbar is a critical component in a power substation.
