In electric power distribution, a busbar (also bus bar) is a metallic strip or bar, typically housed inside switchgear, panel boards, and busway enclosures for local high current power distribution. They are also used to connect high voltage equipment at electrical switchyards, and low-voltage equipment in battery banks. They are generally uninsulated, and have sufficient stiffness to be supported in air by insulated pillars. These features allow sufficient cooling of the conductors, and the ability to tap in at various points without creating a new joint.
The busbar''s material composition and cross-sectional size determine the maximum current it can safely carry. Busbars can have a cross-sectional area of as little as 10 square millimetres (0.016 sq in), but electrical substations may use metal tubes 50 millimetres (2.0 in) in diameter or more as busbars. Aluminium smelters use very large busbars to carry tens of thousands of amperes to the electrochemical cells that produce aluminium from molten salts.
A busbar must be sufficiently rigid to support its own weight, and forces imposed by mechanical vibration and possibly earthquakes, as well as accumulated precipitation in outdoor exposures. In addition, thermal expansion from temperature changes induced by ohmic heating and ambient temperature variations, and magnetic forces induced by large currents, must be considered. To address these concerns, flexible bus bars, typically a sandwich of thin conductor layers, were developed. They require a structural frame or cabinet for their installation.
Distribution boards split the electrical supply into separate circuits at one location. Busways, or bus ducts, are long busbars with protective covers. Rather than branching from the main supply at one location, they allow new circuits to branch off anywhere along the busway.
Busbars may be connected to each other and to electrical apparatus by bolting, clamping or welding. Joints between high-current bus sections often have precisely machined matching surfaces that are silver-plated to reduce contact resistance. At extra high voltages (more than 300 kV) in outdoor buses, corona discharge around the connections becomes a source of radio-frequency interference and power loss, so special connection fittings designed for these voltages are used.
Thanks to their ability to cut pollutants and climate-altering greenhouse gas emissions while keeping noise levels to a minimum, electric buses improve living conditions for urban residents. and increase the electrification of transport. Which explains why, unsurprisingly, they are finding increasing use not only in terms of urban public transport, but also as alternatives to petrol-powered school and shuttle buses.
Passengers enjoy a comfortable ride, thanks to pneumatic suspension technology and the positive experience on board has seemingly translated into greater civil respect for the vehicles. Studies have shown a greater willingness to comply with civic rules and to respect the community from the introduction ol electric buses, with a reduction in fare evasion and graffiti markings.
An electrical substation serves as a critical hub in the power transmission and distribution system. One of the key components of a substation is the electrical bus. This term may evoke images of a vehicle transporting passengers, but in this context, it refers to a completely different concept.
An electrical bus in a substation is essentially a conductor or a group of conductors that serve as a common connection point for two or more electrical circuits. It acts as a junction where multiple transmission lines converge. The bus is typically energized at all times, and all circuits connected to it can draw power from it.
The design and configuration of the bus play a significant role in the operation and reliability of the substation. There are several types of bus configurations, each with its own set of advantages and trade-offs. Let''s get to know some of them:
