...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.

What is the bus bar size for 6000A?
5-6x150 Cu. BUS BAR PER PHASE
What is an infinite bus bar?
A theoretical bus that can provide infinite amounts of current. This is often used in distribution level load studies - the distribution source bus is often modelled this way. The majority of voltage drop is due to the modelled distribution lines, and the step down transformers to the distribution bus often use load tap changers to keep the source voltage at the desired level anyway.It's a electrical term relating to power grids. See the Related Link below.
What is z bus of power system?
Z bus is using in fault analysis of power system..it represents how much impedance the network offers to the fault current.lower the impedence larger the fault current
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...
Compressed air system for bus bar?
To avoid accumulation of moisture.
How many pounds does a 2 ton bus weigh with no gravity?
A two-ton bus would have zero weight in zero gravity, since weight is dependent on the force of gravity. However, gravity has an infinite range, so gravity would only actually be zero at an infinite distance from the source of the gravity.
What is purpose of ct supervision relay in high impedance bus bar protection?
A high impedance bus bar relay uses summed CTs from multiple breakers into a high resistance to determine a fault condition. Since all CTs connect to a single input on the relay, the relay cannot determine if a valid fault condition has occured, or one of the CTs is disconnected (open circuited). External CT supervision must be supplied to confirm.
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.
In a bus network if the ends of the cable aren't terminated What is occurs?
The unterminated end presents an impedance mismatch or 'bump'. This causes a reflection of the original signal to propagate back down the bus, which destructively combines with and degrades the desired waveform. For this to be avoided, the bus must be terminated with a resistance equal to its characteristic impedance.
How can a bus have infinite space in it?
Because, when your on a bus, even though it looks full, someone always seems to be able to hop on without anyone hoping off. So by rights, the bus has infinite space.
What is the bus bar size for 6000A?
5-6x150 Cu. BUS BAR PER PHASE
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.

What does the term 'bus bar' refer to?
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.
How do you convert bus bar to amp?
Bus bar is a physical component that carries the current. AMP is unit of current. They can not be converted
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 Slowest Computer Bus?
The slowest computer bus would be a stopped or halted computer bus, since there would be infinite time between operations.
