1. Busbar protection
Most of the time, a fault on a busbar is very hard on the network (high short-circuit current and large number of structures to be taken out of service to eliminate the fault). It must therefore be eliminated quickly. Without specific protection, such a fault is eliminated by the distance protection of adjacent substations within a 2nd zone time (250 to 600 ms) in the most favorable case (see
The role of busbar protection is to improve the situation by eliminating any type of fault occurring in the busbar area as quickly and selectively as possible....
