Busbar Protection Schemes

This is the simplest way of shielding the bus-bar from faults. The supplying system is the cause of the bus-bar fault. Thus, the supply system is protected by backup. The primary purpose of such a system is to protect the transmission lines. However, because the protective system is so reasonable, bus-bar protection is also an application for it.
