BUSBAR PROTECTION
Busbar protection may simultaneously trip a number of bus segments or even an entire busbar of a substation and the fast elimination of busbar faults is critical to ensure that the transmission system

The testing of busbar protection schemes will therefore necessitate particular care over CT polarities, correct operation of busbar selector auxiliary contacts and primary operating current at the selected
Busbar Differential Protection Scheme
In the early days, only conventional over-current relays were used for busbar protection. The goal was to ensure that faults in any feeder or transformer connected to the busbar did not affect
