busbar \busbar\, bus-bar \bus-bar\n. an electrical conductor that makes a common connection between several circuits.
Syn: busbar, bus.
alt. An electrical conductor that carries a large current, especially one that is part of a power distribution system ; typically a thick strip, or a tube, of copper or aluminium. n. An electrical conductor that carries a large current, especially one that is part of a power distribution system ; typically a thick strip, or a tube, of copper or aluminium.
n. an electrical conductor that makes a common connection between several circuits; "the busbar in this computer can transmit data either way between any two components of the system" [syn: bus]
In electrical power distribution, a busbar (also spelled bus bar, or sometimes as buss bar or bussbar, with the term bus being a contraction of the Latin omnibus, "for all", or buss being short for buttress) is a metallic strip or bar (typically copper, brass or aluminium) that conducts electricity within a switchboard, distribution board, substation, battery bank, or other electrical apparatus. Busbars are used to carry substantial electric currents over relatively short distances; their greater surface area (compared to a wire of the same weight) reduces losses due to corona discharge. Busbars are not normally structural members.
The material composition and cross-sectional size of the busbar determine the maximum amount of current that can be safely carried. Busbars can have a cross-sectional area of as little as , but electrical substations may use metal tubes in diameter or more as busbars. An aluminium smelter will have very large busbars used to carry tens of thousands of amperes to the electrochemical cells that produce aluminium from molten salts.
