friends, today I am going to tell you that the Transposition Of Overhead line Conducters, Advantages of Transposition in Overhead Line : If you also want to know, then keep reading this article completely.
Transposition Of Overhead Line Conductors
When a communication circuit goes along the same path along a high potential power line, interference, electromagnetic and electrostatic effects are produced in such a communication system. This electromagnetic effect produces electric currents in the communication line, which distracts the sound and increases the potential of the entire circuit.
Due to these effects, the nature of the transmitted sound is changed to noise. To solve this problem, the transmission line is done in the communication system. Changing the phase sequence of the conductor of the overhead line is called Transposition of Overhead Line Conductors.

The transposition effect balances the capacitance of the line’s efficiency. The electrostatic current is balanced by a barrel of input potential transposition. The electromagnetic induced force is also reduced because the positive and negative phase currents interact with each other in the transposition. Destroys. Therefore, the translocation of the telephone line also becomes necessary.
Shifting drivers is necessary because due to atmospheric effects like a strong storm, storms, wind, snow, heat etc., the sagging of overhead lines increases. This makes the distances between the two lines unequal. The value of the line parameter changes because the inductance and capacitance reactance of the line depends on the distance between the conductors. To keep the value of the line parameter balanced, it is necessary to change the phase value of the overhead line.
Advantages of Transposition in Overhead Line
(1) Transposing the conductor through a constant gap, the inductance and capacitance remain the same.
(2) When there is a telephone line parallel to the conductor, the possibility of high voltage generation in the telephone line increases, due to which there is noise in the conductor. The static gap reduces this phenomenon.
(3) In practice, it is done in switching stations and sub-stations.
