Busbar Protection Considerations When Using IEC 61850 Process Bus

Busbar protection systems protect substation busbars and associated equipment from the consequences of short-circuits and earth faults. In the early days of power system development no separate protection device was used for busbar protection. Remote end-line protections served as the main protection for busbar faults. As a result of increased network short-circuit capacity, dedicated differential relays for busbar protections have been applied to limit the damage caused by high fault currents.
