Question

Question: In a three-phase line, in order to avoid unequal phase inductances due to unbalanced flux linkages, what technique is used?

Short answer

Answer

Therefore, the transpositions of the conductor technique is used to avoid the unequal phase inductance due to unbalance flux linkage.

Step-by-step solution

concept of the unequal flux linkage in the transmission line. 

The power system should have remained in a balanced condition, and to maintain this balance in the system, the spacing between the conductor of the transmission line should be the same.

The spacing of the conductor should be same to maintain the balance of the power system.

The asymmetrical spacing of the conductor results in unequal flux linkage, resulting in the energy exchange between the phases. So, to maintain the balance, the position of the conductors is exchanged along the line.
