In , a busbar (also bus bar) is a metallic strip or bar, typically housed inside,, and for local high current power distribution, transmission, or switching substations. They are also used to connect high voltage equipment at electrical switchyards, and low-voltage equipment in. They are generally uninsulated, and have sufficient stiffness to be s.
The circuit configurations for high- and medium-voltage switchgear installations are governed by operational considerations. Whether single or multiple busbars are necessary will depend mainly on how the sys.
