What is difference between bus coupler and bus section?
The bus sectionalizer is used in switchgear having a Single Busbar Configuration to divide the bus into two Sections; while bus coupler is normally used in switchgear having Double Busbar Configuration to Connect the Two buses in case of load transfer, contingencies, etc.
What is double bus bar?
In double bus bar system two identical bus bars are used in such a way that any outgoing or incoming feeder can be taken from any of the bus. Actually every feeder is connected to both of the buses in parallel through individual isolator as shown in the figure.
What is a bus riser in electrical?
Bus riser is a set of bus bar that connected from the coupler breakers, outgoing section enclose in the panel and connected to your incoming 1 or incoming 2 bus bar section. It depend which side is your outgoing from the bus bar coupler breakers or depend on your electrical design.
What is a 12v bus bar?
A bus bar is designed to make a solid connection point from one source to many branch circuits. More often than not a bus bar is used on the negative side of the circuit, because the switch panel is used as the positive source distribution method.
What are the four types of buses?
Buses
- Address bus – carries memory addresses from the processor to other components such as primary storage and input/output devices. The address bus is unidirectional .
- Data bus – carries the data between the processor and other components.
- Control bus – carries control signals from the processor to other components.
What is common bus?
The basic computer has eight registers, a memory unit, and a control unit . Paths must be provided to transfer information from one register to another and between memory and registers. A more efficient scheme for transferring information in a system with many registers is to use a common bus. …
What is bus section in substation?
The electrical substation is a junction point where two or more transmission lines terminate. A substation bus scheme is the arrangement of overhead bus bar and associated switching equipment (circuit breakers and isolators) in a substation.
What is bus current?
In power engineering, a “bus” is any graph node of the single-line diagram at which voltage, current, power flow, or other quantities are to be evaluated. This may correspond to the physical busbars in substation.
What is a bus Riser in electrical wiring?
A bus riser is a cubicle designed to receive incoming cables from below and connect them to horizontal bus bars between adjacent cubicles in a run of switchgear. The connection between the cable and the bus bars may be direct, or via some sort of disconnected, which may be an off-load isolator, an on-load circuit breaker, Fuses, etc.
What is riser cable and why is it important?
They get their name because of the way riser cable is ran which is rising up to each floor. Riser cable is important in that it can be a buildings backbone that transmits data, audio and video signals. The way Riser cable is termed through the industry is “CMR” which stands for communications riser.
What does busriser mean?
Busriser means When your outgoings or Incomers are busbars rather than cables,and it runs through an enclosed Busduct upto the destination. There are no shortcuts on the road to a great experience. No more “Almost” Good Answers.
What is bus coupler and how does it work?
Bus coupler is just a breaker which is used to couple two bus bars in order to provide maintenance for the devices connected to one bus bar while the other bus bar will be functional. The continuity of the supply remains the same even in the case of fault. When the faults occurs in any one of the buses the entire load is shifted to another bus.
