(1) For a given load there are less losses along a d.c. transmission line.
(2) There are no synchronisation problems when linking independent a.c. grid systems.
(3) There are no a.c. capacitive-loss currents in d.c. undersea cables, whose capacitance is large, due to closeness of line conductors.
What else can I help you with?
Where would DC be used instead of AC?
DC is used for extra-high voltage transmission systems, as there are less losses with DC than with AC, and no synchronising problems.
How do you write a persuasive speech about why DC current is better than AC?
I think you would have a problem with that since a transformer won't work on DC and the power transmission boys would have a fit.
What is the difference between in ac and dc powwer cable?
There is no difference in the cables. The only difference is the type of electrical power being transmitted. AC or DC applications use the same wires.
Why AC current is transmitted from power station instead of DC current?
This was due to the results of the War of the Currents between Edison, who supported DC and Tesla for AC power distribution. Although most electronics you find today run off DC power, the transmission of DC power over long distances is not very efficient and requires several substations between the power transmission source and where it is received. AC power after stepped up can be transmission over long distances with little energy loss. The energy loss occurs from heat generated from resistance within the transmission wire. At the introduction of Edison's system, there was no practical AC motor available. It was primary due to the introduction of the 3 phase AC motor did AC finally win over DC.
Do trains use ac or dc elecricity in the UK?
train uses acpower as its source.as in case of dc there would be only steady state conditions and transmission distance would be low.but in ac,it is sinusoidal waveform and transmission of power source can be done at a larger rate with high effeciency and minimal lose.so ac source is used in electric trains.
Do you get DC current directly from the transmission line?
Only if it is a DC transmission line.
Why dc supply cannot be given to transmission lines?
We can use DC too for the transmission system. Refer HVDC transmission system.
What is theadvantage of a Z71 engine?
nothing its a suspension package
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.
Where would DC be used instead of AC?
DC is used for extra-high voltage transmission systems, as there are less losses with DC than with AC, and no synchronising problems.
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.
Which power transmission is best ac or dc?
yes, i think dc transmission is best, coz in dc losses is low, no iductance between conduct, less corona loss.AnswerNeither is 'better'; they each have advantages and disadvantages. For example, although there might be less losses with d.c. transmission, the equipment required to raise and reduce the voltage at each end of the line is more costly than for an a.c. transmission system.
Why ac prepared DC current?
because the transmission cost of ac supply is lesser than dc. thats why ac is prefered
Is AC better than DC in terms of electrical power transmission efficiency?
AC is generally more efficient than DC for long-distance electrical power transmission because it can be easily converted to higher voltages, reducing energy losses during transmission.
Why there are no losses in DC transmission?
There are losses in d.c. transmission lines, due to their resistance. But there are no reactive losses. So, d.c. transmission lines have less losses in comparison to an equivalent a.c. transmission line.
Why is not impractical to power distribution in power DC?
IN DC FOR LOW VOLTAGE HIGH DENSITY OF CURRENT WILL BE THERE SO WE CAN NOT USE THIS FOR BEST PRACTICE FOR TRANSMISSION & ALSO BECOS OF HIGH CURRENT TRANSMISSION LOSSES ARE VERY HIGH ( I2XR) LOSSES, TRANSMISSIN EQUIPMENT FOR DC ARE HIGH COSTIN DC FOR LOW VOLTAGE HIGH DENSITY OF CURRENT WILL BE THERE SO WE CAN NOT USE THIS FOR BEST PRACTICE FOR TRANSMISSION & ALSO BECOS OF HIGH CURRENT TRANSMISSION LOSSES ARE VERY HIGH ( I2XR) LOSSES, TRANSMISSIN EQUIPMENT FOR DC ARE HIGH COSTAnswerThe main reason is that we cannot use transformers to easily and efficiently change the magnitude of DC voltages, and the ability to change voltages is essential for electricity distribution. However, having said that, very high-voltage transmission over exceptionally long distances is often done using DC. This is because DC losses are far lower than AC losses.
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
