A busbar is a length of flat, rectangular-section, copper used as a common point of connection for a number of electrical conductors that share the same potential. The term has the same derivation as 'omnibus', meaning 'serving several objects', and its correct spelling is busbar or bus bar, not'bussbar'!

For DC or single-phase applications, two busbars (physically in parallel with each other) are required -one at a positive potential and the other at a negative potential (DC) or one for the line and the other for the neutral. Often a third busbar is provided for neutral conductors and a fourth for the earth (ground) conductors. For three-phase systems, three busbars are required -one per line- and, possibly, one for the neutral and yet another for the earth.

Busbars are found in a variety of places, from those operating at thousands of volts in outdoor and indoor substations, down to those operating at hundreds of volts in residential circuit-breaker panels.

Why the impedance of infinite bus bar is zero?

...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.


The purpose of the bus bar protection unit is to isolate any bus by tripping its contactor or isolate a faulty bus in the variable ac system?

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...


How do you make 3 ply bus bar bending?

To make a 3-ply bus bar bending, first, gather the necessary materials, including the bus bar, bending tools (like a hydraulic or manual bender), and safety equipment. Measure and mark the desired bending points on the bus bar, ensuring precise angles for functionality. Position the bus bar in the bender, align it with the marks, and apply pressure gradually to achieve the required bends. Finally, verify the bends for accuracy and ensure they meet the specified electrical and structural requirements.


How you calculate the proper size of copper bus bar for 1200 Kw load?

You first have to find out what the load amperage is going to be and second, what is the working voltage.

How can you calculate the copper bus bar according to the amp?

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.

What are the types of bus bar arrangements?

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.

Difference between bus bar and bus duct?

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


What is the difference between a 200 amp bus bar and a 150 amp 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.
