Literature review has shown that small distribution substations used for medium voltage make use of overcurrent relays to provide busbar protection and large substations make use of differential protection schemes. This technical article explains a busbar theory at the. A busbar is a strip or bar of copper, brass or aluminum that conducts electricity within a switchboard, a substation or a battery bank. Its purpose is to conduct a substantial current of electricity. ABB's busbar protection is designed for phase-segregated short-circuit protection, control, and. Busbar protection (BBP): Protection intended to detect and operate to clear faults on a busbar. 35kV high voltage busbar heat shrink tubing is widely used in the insulation protection of high-voltage switchgear busbars, thanks to its outstanding insulation performance and flexibility, effectively preventing the risk of accidents caused by exposed live wires. Protecting these busbars from faults is essential to ensure grid stability and prevent widespread outages. Two primary protection schemes are employed: high.
