Read MoreHome / What does busbar shutdown at high-voltage switchgear mean
When a busbar fault occurs, the BBP will trip all circuits connected to the busbar, shutting down the entire substation. Busbars have typically been left without dedicated protection, from the following reasons: It is a fact that the risk of a short circuit happening on modern metal clad equipment is insignificant, but it cannot be completely dismissed. Protecting these busbars from faults is essential to ensure grid stability and prevent widespread outages. An electric busbar is defined as a single conductor or a group of conductors that serve the purpose of collecting electrical power from incoming feeders and distributing it to outgoing feeders.
