An alternating current tends to flow on the edge of conductor rather than its centre known as 'skin effect'. Therefore, hollow busbars are used as it provides enough surface area without the much use of copper and aluminium.
To obtain the amp of the copper bus bar, multiply the width of the bus bar by the thickness of the bus bar to obtain the current carrying capacity of the bus bar.
Single bus is used in smaller, less important substations. A fault on the bus requires tripping of all lines into the bus. When higher redundancy is necessary, ring and breaker and 1/2 schemes are used. These are the three most common.
Bus bars are actually simple conductor strips of copper using for connection between one system to another.for example transformer to panel. bus ducts are enclouser of that bus bar
The primary difference between a 200 amp bus bar and a 150 amp bus bar lies in their current-carrying capacity. A 200 amp bus bar can safely handle a maximum load of 200 amps, making it suitable for larger electrical systems, while a 150 amp bus bar is limited to 150 amps. This difference affects their applications; a 200 amp bus bar is typically used in larger service panels or commercial settings, whereas a 150 amp bus bar may be adequate for smaller residential systems. Additionally, the physical size and material specifications may vary to accommodate the different current ratings.
Double bus bar is related to power control center (PCC). PCC is the main LT power distribution in any industrial establishment or large residential complex too. It basically an electrical panel with required number of incomer feeders and outgoing feeders. Power source like state power or captive power provide the incomers and outgoing feeders cater to the down stream power panels for further distribution( to MCC). Any PCC has one or more incomer and one or more outgoing feeder and bus isolators depending on the requirement. This PCC needs to have a bus bar to which the incomer gets connected and feeds the power to the bus and the outgoing feeders are connected to the bus bar to deliver the power down stream. This bus bar can be single bus bar system or double bus bar system. In a double bus bar system the two different power sources are connected to two different bus. Say one bus is for DG set power another bus is for SEB power. Both the buses can be charged simultaneously and can feed any outgoing feeders. The out going feeder have flexibility of getting the power either of the buses, but not simultaneously from both the buses. Double bus bar is more expensive compared to single bus bar system but more flexible, reliable.
To obtain the amp of the copper bus bar, multiply the width of the bus bar by the thickness of the bus bar to obtain the current carrying capacity of the bus bar.
The Bus Bar is (usually 3, or 4) solid copper bars that run through an MCC (Motor Control Center) and just supply power to the individual 'buckets' (compartments that contain the individual motor starters). The only protection for a bus bar would be from the 'Panelboard', or 'Switchboard' breaker that feeds the bus bar mounted in a separate MCC. Make Sense???, let me know if not...
The purpose of a bus bar in an electrical panel is to distribute electrical power from the main power source to the various circuits within the panel. It acts as a central point for connecting and distributing electricity to different components in the panel, ensuring a safe and efficient flow of electricity throughout the system.
The purpose of the neutral bus bar in an electrical panel is to provide a connection point for the neutral wires from the electrical circuits in a building. This helps to ensure that any excess current flows back to the electrical source, maintaining a balanced electrical system and preventing electrical hazards.
5-6x150 Cu. BUS BAR PER PHASE
Single bus is used in smaller, less important substations. A fault on the bus requires tripping of all lines into the bus. When higher redundancy is necessary, ring and breaker and 1/2 schemes are used. These are the three most common.
The volume of a square hollow bar is calculated by multiplying the length of the bar times the width of the opening times the height of the opening ( inner dimensions ).
Its a switch
The term "bus bar" refers to a strip of bar of brass, aluminum, or copper. This strip of bar conducts electricity with a distribution and switch board.
Bus bar is a physical component that carries the current. AMP is unit of current. They can not be converted
function of a bus shelter
...because it is an infinite bus bar, meaning it can supply infinite current. By Ohm's law, since the voltage at the bus bar is fixed, to have infinite current, you must have a zero impedance.
