There are no applications for losses, that's why they are called 'losses'!

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 compute energy loss in transmission line?
Energy loss is I^2*R losses. Calculate the transmission line resistance, and multiply by the current squared per unit time (seconds if in watt/seconds, for example).
Why is high voltage a plus?
its because of transformers . they work with pulse
What is the effect of frequency change on transmission losses?
Higher the frequency, higher the losses.
Why transmitting of power at high voltage is economical?
For a given load, the higher the supply voltage, the lower the resulting load current. So, using high-voltages in transmission systems (1) avoid enormous voltage drops along the line, (2) enable cables of realistic cross-sectional area and weight to be used, and (3) minimise line losses. So, high-voltage transmission requires less copper and avoid line losses -resulting in lower costs.
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 does a 2003 impala transmission loses power?

Why transposition tower in long transmission line?
In transmission line minimum 3 conductors are run in parallel. Every conductor has a flux which produce losses in other conductor which is run with parallel. So in the middle one conductor the losses is double in respect to other two conductors. At the end of the line the voltage of the middle one conductor is reduced from other conductors due to these losses. The transposition tower is used to change the conductors. By using these tower we shift each conductor position. So we use these towers in long transmission line so that these losses becomes equal for each conductor. and voltage will be almost equal at the end of the transmission line. Regards. Vishal kr.

Why transmission line voltage is like 6.6kv 11kv22kv 33kv etc?
Usage of such high voltages will increase the efficiency of the transmission lines and decreases the losses in the line. It also reduces the requirement of conductor size.
Why are transmission voltages in multiples of 11?
Transmission voltages are in multiples of 11 to allow for 10% transmission line losses. Therefore, to obtain 100% efficiency, voltages in multiples of 11 are transmitted.
How do you compute energy loss in transmission line?
Energy loss is I^2*R losses. Calculate the transmission line resistance, and multiply by the current squared per unit time (seconds if in watt/seconds, for example).
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...
Why is high voltage a plus?
its because of transformers . they work with pulse
Why higher voltege required for long transmission line?
To (a) eliminate high voltage drops along the line, (b) to allow conductors of practical size to be used, and (c) to reduce line losses.
What has the author Omar Siddiqui written?
Omar Siddiqui has written: 'Resonance-cone propagation in continuous transmission-line grids and microwave applications'
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.
