What is difference between advantage and disadvantage AC and DC power transmission line?
The main advantage of ac- it required less maintainance The main disadvantage of ac-it can not be stored the main advantage of dc -it required less amount of conductors to transmit and easily stored The main disadvantage of dc-it is more dangerous than ac at high voltage
Why you use ac for transmission?
AC is used for transmission because AC can be stepped up in voltage with a transformer, and then stepped back down at the destination. Since power is voltage times current, a higher voltage requires a smaller current to achieve the same power. Since the current carrying capacity of wires is based on wire size, a smaller wire size can be used to transmit the lower current.
Lines BE and AC are?
letters of the alphabet
Why are transmission voltages in ac systems generally higher than those in dc systems?
The main advantage of using ac is that you can step up and step down the voltage by means of a transformer,since transformer works only with ac. another thing is that if dc power is used for transmission,then the power loss associated with t will demand the use of transmission lines which are very thick(have a larger cross section)..for long distance transmission this may lead to the requirement of power lines with impractical dimensions.
Why is it more economical to transmit a ac supply rather than a dc?
They use both. AC is almost universally used because it is easy to convert it to different voltages by step up or down transformers. Over very long distances and in special circumstances DC is used because AC has higher losses. The phase synchronization with other power grids as well as the frequency is also a problem with AC. A common example is where 50 Hz and 60 Hz power systems share resources.
How do you transmit ac power flow in HVDC transmission line?
You don't! That's the whole point of a d.c. transmission line.
How many phase are there from transmission line from Oregon?
AC transmission lines are 3-phase, DC transmission lines don't have phases. It doesn't matter where they are from.
Why you use ac current of home instead of dc?
alternating current is generally instantaneous in nature and even in transmission lines it is easy to transmit with less losses when compared to dc as because it possess frequency where as dc do not have
Why do transmission lines use alternating current instead of direct current?
Transmission lines use alternating current (AC) instead of direct current (DC) because AC can travel long distances with less energy loss. AC can be easily converted to higher or lower voltages using transformers, which is important for efficient power distribution. Additionally, AC allows for easier control and regulation of power flow in the grid.
How does AC power work and what are its key components in an electrical system?
AC power, or alternating current power, works by constantly changing the direction of the flow of electricity. This allows for efficient transmission of electricity over long distances. The key components in an AC electrical system include a power source (such as a generator or power plant), transformers to change the voltage levels for transmission, transmission lines to carry the electricity, and distribution lines to deliver power to homes and businesses.
Why do we use AC supply in our homes?
The power transmission would require bigger wires to transmit high dc current so instead high voltage ac current is transmitted through long distance linesTo reduce losses it is necessary for the value of current through lines to be lowTranformers donot work for dc current so one cant step up and step down dc current voltage like it can be done with ac current
What is difference between advantage and disadvantage AC and DC power transmission line?
The main advantage of ac- it required less maintainance The main disadvantage of ac-it can not be stored the main advantage of dc -it required less amount of conductors to transmit and easily stored The main disadvantage of dc-it is more dangerous than ac at high voltage
Can you put a 2.4 engine in place of a 3.7 engine in a 2003 jeep liberty sport?
No. You would need the transmission, wiring, fuel lines, computers, ac lines, and radiator hoses for a 2.4L.
Why you use ac for transmission?
AC is used for transmission because AC can be stepped up in voltage with a transformer, and then stepped back down at the destination. Since power is voltage times current, a higher voltage requires a smaller current to achieve the same power. Since the current carrying capacity of wires is based on wire size, a smaller wire size can be used to transmit the lower current.
What is a transmission lines?
An AC transmission line is typically a set of three wires that transports electricity over great distances at potentials exceeding 115,000 Volts. A common intrastate transmission line voltage is 230,000 Volts (230 kV), and interstate lines are normally rated 500,000 Volts (500 kV). When it is desired to transport electricity to a non synchronized area -- like Texas, DC transmission lines are used instead.
How did George Westinghouse revolutionise electricity?
He adopted Nikola Tesla's system of Alternating Current generation and transmission using step up and step down transformers via a grid network. This was against the advice of Thomas Edison who was committed to Direct Current and all it's inherent flaws. You cannot transmit DC ascross country and get a useful amount of power out at the other end.
Who is better ac or DC transmission?
ac transmission is better. because it is cheaper as converter are not use.but losses are more as comparison to dc.
