To reduce power losses in transmission lines the voltage is made?
Much higher.
What is the purpose of having a low impedance for transmission lines?
in order to reduce the transmission line losses we need low impedance...Low impedance also improves power transfer capacity of the line..
How do you reduce radiation loss in transmission lines?
Transmission loss reduce by using 1) higher diameter conductor (R = q l / a) or specially maded low loss conductors 2) using energy efficient equipment such as low loss transformer 3) twisted conductors instead of solid 4) proper monitoring and control of transmission eqipment 5) use of high temperature super conductors ....etc
What are the advantages of 750Kv high voltage?
A high voltage like 750kV is used in transmission lines because this reduces the current in the wires for a given amount of power. A reduced current will reduce the power lost in transmission (I^2R).CommentFar more importantly than reducing line losses, it reduces the voltage drop along the line which would, otherwise, be enormous!
Why are ultra high voltages used to carry electricity over transmission lines?
In general, it is cheaper to transport power long distances at higher voltage levels. Do not take this as a rule as always being cheaper, otherwise you would have a 500kV line into your home.The resistance in the power company's lines is not zero. There is always going to be some loss in quality whenever energy is transferred. Thus, when electricity is transferred, the power dissipated by the lines, even lines with a REALLY small resistance, like 1 micro-ohm per mile, adds up when one counts the millions of linear miles across which electricity is transmitted. The power dissipated can be calculated with the formula, P= VI, which through Ohm's law becomes P = (I^2) x R, where P = Power dissipated, V = voltage, I= current, and R= resistance. Thus, using the same resistance wire and the same power source, a higher voltage will have a lower current and less power will be dissipated as heat.It is not cheaper to transport electric power at high voltages. What we are looking for is the smallest amount of loss during that transfer. The higher the voltage the lower the percentage of loss for a given diameter of wire. The costs associated with stations to step up and down power and to maintain these stations is very high. What the goal is here though is making as much power as possible reach our final destination. This is also why we use aluminum wire for transfer rather then copper. It is all about reduced loss, cost is a secondary concern.

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.

What is a set of standards for digital transmission of data over standard copper telephone lines?
The set of standards for digital transmission of data over standard copper telephone lines is ISDN
What is signal distortion in transmission lines?
there are some distortion in transmission line : copper loss,dielectric loss,skin effect
Why copper is used in electrical transmission line?
Copper is a good conductor and is fairly strong. It generally is not used in power transmission lines due to cost - generally aluminimum is used.
Is aluminum a semiconductor?
No, it is a conductor. It doesn't conduct as well as copper, but it conducts well enough that it's commonly used in high-tension electrical lines (it weighs much less than copper and it's a lot cheaper; those two factors offset the transmission losses).
What does power loss in electrical transmission mean?
The term, 'power loss', describes the rate of energy losses caused by the load current in the transmission lines

Is reactance major responsible for power loss in power transmission lines?
Reactance certainly causes loss in a transmission system, but I^2R or resistance losses are greater.
What are the advantages of using copper compared to aluminium for transmission lines?
Copper is a better conductor than aluminum. Two wires with the same cross-sectional area, or any two constructs with the same physical shape and size, one fabricated from aluminum and the other from copper, the one made of aluminum always has higher ohmic resistance.
What are the Advantages of Corona in transmission lines?
Due to corona effect virtually conductor size is increase and therefor resistance in transmission line is decreases.so I2R losses will decreases...
