Why bus bar is rectangular?
Busbars are not necessarily rectangular. Those used in substation compounds are frequently tubular in construction.
What is tertiary bus in substation?
Many substation transformers have three windings - the primary, secondary, and tertiary. The tertiary bus is the bus connected to the tertiary of the transformer. this is often used as station power for the substation, since the tertiary is very often a distribution level voltage (2 - 15kV).
What is the difference between a line isolator and a bus isolator?
If I'm interpreting the question accurately, a "line isolator" is an insulating standoff for transmission or distribution cable. A bus isolator is an insulating standoff for tubular or bar bus as is normally seen in a substation switching yard.
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.
Are neutrial and ground wires to be separated in electric main box?
Yes, if possible, connect the grounds to the ground bus bar and the neutrals to the other side on the neutral bus bar. This is just in case you ever install a sub panel. It is not a violation of the NEC code to connect them to the same bus bar but IMO it is unprofessional and can cause problems later on.

What is an Electrical substation ring bus?
The substation ring bus is a conducting bar, which can connect one or more incoming lines and no of out going lines (or) feeders. The ring bus is connected to the line through isolator, circuit breaker and other protective devices. Rajendran Arputharaj k M.E.(Power systems Engg.)

What is the meaning of diameter in power substation diameter refers to transformer bay or transmission line bay in a substation?
A arrangement of Equipment between two bus-bars. Example 1 and 1/3, 1 and half etc.
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
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.
