What is a bus in a power system?

A bus is a node where a line or several lines are connected and may also include several components such as loads and generators in a power system. Each bus or node is correlated with one of four quantities: (1), magnitude of voltage, (2) phase angle of voltage, (3) active power or true power, and (4) reactive power.

What is the purpose of a busbar?

Busbars distribute electricity with greater ease and flexibility than some other more permanent forms of installation and distribution. Sometimes spelled bus bar or buss bar, they are often metallic strips of copper, brass, or aluminum that both ground and conduct electricity.

What does bus stand for in electronics?

“In computer architecture, a bus (from the Latin omnibus, meaning “for all”) is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.) and software, including communication protocol.”

What are the 3 types of power supply?

There are three subsets of regulated power supplies: linear, switched, and battery-based. Of the three basic regulated power supply designs, linear is the least complicated system, but switched and battery power have their advantages.

What is per unit value?

Definition: The per – unit value of any quantity is defined as the ratio of actual value in any unit to the base or reference value in the same unit. Any quantity is converted into per unit quantity by dividing the numeral value by the chosen base value of the same dimension. The per – unit value is dimensionless.

What happens if you touch a busbar?

so the effect of touching a busbar are the same as that of touching a conductor. But you touch busbar while standing the ground, there is a contact between the line to ground and there will create a L-G fault. you will receive a heavy electric shock before the CB trip and it is enough to cause death.

What is busbar trunking?

Busbar Trunking System is the is a system of distributing electric power using copper or aluminium busbar with suitable enclosures and good amount of protection to prevent the cables from getting damaged due to foreign bodies. Busbars are now becoming irreplaceable simply because of the convenience and safety factor.

What is busbar voltage?

Definition: An electrical bus bar is defined as a conductor or a group of conductor used for collecting electric power from the incoming feeders and distributes them to the outgoing feeders. In other words, it is a type of electrical junction in which all the incoming and outgoing electrical current meets.

What are the 3 types of buses?

Three types of bus are used.

  • Address bus – carries memory addresses from the processor to other components such as primary storage and input/output devices.
  • Data bus – carries the data between the processor and other components.
  • Control bus – carries control signals from the processor to other components.

What does bus mean?

1: to travel by a large motor vehicle designed to carry passengers usually along a fixed route according to a schedule: to travel by bus. 2: to work as a busboy. transitive verb.

What is bus speed?

Bus speed usually refers to the speed of the front side bus (FSB), which connects the CPU to the northbridge. FSB speeds can range from 66 MHz to over 800 MHz. Since the CPU reaches the memory controller though the northbridge, FSB speed can dramatically affect a computer’s performance.

Why DC is not used in homes?

The answer to why DC current is not used in homes goes back to the inherent characteristics of direct currents and their weaknesses compared to Alternating Currents (AC). In fact, AC currents can be easily transmitted over long distances without much loss. They are also safer in direct touch at an equal voltage.

Do computers run on AC or DC?

A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage.

Are plugs AC or DC?

When you plug things into the outlet in your house, you don’t get DC. Household outlets are AC – Alternating Current.
