The balancing effect on account of irregular spacing of conductors can be avoided by changing the position of the conductors at regular distances. this is called transposition of conductors. In case of 3- phase transmission lines, the inductance and capacitance of each phase will be different if the three conductors are spaced differently (each phase to the other two phases, and each phase to ground). the apparent resistance of the conductors is also affected on account of transfer of power between the phases which occur due to mutual coupling. so all the three parameters of the transmission lines are affected by irregular spacing of the conductors.

What is pg clamps in transmission line?
pg clamp is known for parallel groove clamp,especially used in transmission line to hold transmission conductors in parallel.
What is the line voltage of a 230000 kv transmission line?
Transmission and distribution voltages are normally expressed in terms of line voltages, so the answer is that the figure you quote is a line voltage. Incidentally, do you really mean 230 megavolts for a transmission voltage?? And the symbol of kilovolt is 'kV', not 'kv'.
Which type of transmission line will have max value of characteristic impedence?
coaxial cable

Could it be dangerous to connect an alternator to a long transmission line if the line had a high capacitance?
Yes. Because... If we connect an alternator to a transmission line of high capacitance the line voltage will increase and caused a line voltage difference, which does not satisfied the condition of parallel operation of same voltage rating. [By Akhtaruzzaman08]
Why phases in transmission line are transposed?
Image result for Why phases in transmission line are transposed?Transposition is the periodic swapping of positions of the conductors of a transmission line, in order to reduce crosstalk and otherwise improve transmission. ... Transposition also equalizes their impedance relative to the ground, thus avoiding one-sided loads in three-phase electric power systems.
Why phases in a transmission line need to be transposed?
Transposition means exchanging of the position of the transmission line after equal distances. Even if the voltage across the conductors are equal during the transmission, there will be slight differences and will result in varied inductances of the conductors. Hence if we have symmetrical conductors running through transmission line in a similar fashion, there may be unbalances in voltage. Also mutual inductances vary for untransposed lines.
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.

What are the strength of transposition cipher?
A transposition cipher involves scrambling the letters in a message. The strengths of this are that there is less correspondence between characters, as there is in a substitution cipher, and that it tends to reduce redundancy.
Do you get DC current directly from the transmission line?
Only if it is a DC transmission line.
Is there one coolant line or two for the transmission on a 98 Mercury?
If this vehicle has a transmission cooler then it will have one line to the cooler then another for the return line to the transmission.
