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...
What is the bus bar size for 6000A?
5-6x150 Cu. BUS BAR PER PHASE
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.
Difference between Bus Clock and System Clock in Microcontrollers?
Bus Clock is based on the System Clock. In other terms Bus Clock is derived from system Clock. Bus Clock is usually half System Clock. (Busy Clock = System Clock / 2)
Why we go for bus bar riser system instead of cables?
It is done to carry more current at rated power & to reduce the power loss as compared to cable since a bus-bar has more area compared to cable so resistance is less & hence losses are reduced.

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 makes a bus lorry coach etc rise up when starting to move after standing idle with the brakes on?
Most buses and lorries have what are called air brakes which use compressed air, sometimes you can hear the released compression when it comes to a halt and there's suddenly a sharp burst of air. when the bus comes to a stop it also releases air fom airpistons which drops the bus to kerb level in order to facilitate the elderly, and young children in boarding the bus, also women with buggies etc, after everyone has boarded the bus, the driver switches the bus to normal level and compressed air fills the pistons which then rises the bus to its correct driving position in order for the bus to continue its journey.
How do you increase voltage of distribution bus bar?
A hybrid grid mini-system
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 machiens that operate with compressed air?
Pneumatically powered machines, Bus doors/suspension, automatic doors and light lifting gear.
What is double busbar arrangement?
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.

What are the requirements for the ventilation system bus laws which regulate the temperature of the cabin or the amount of incoming air?
The bus laws requires that all the public bus to have a proper ventilation system to regulate the temperature of the cabin.
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.
What is a kneeling bus?
the bus can lower itself, by letting air out of its suspension system, to allow deployment of a wheel chair ramp. The driver press's a button and it releases the air out of the brakes and the suspension systems
