Protection of High Voltage Busbars from Sharp Points
This involves installing dual, independent protection schemes, often designated as Main Protection A and Backup Protection B. 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. Line protection concepts, such as overcurrent and distance arrangements, satisfy this requirement, even though short circuits in the busbar zone are cleared after certain time delay.
