Directions: It consists of two statements, one labeled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer using the codes given below:
Statement (I): The expression for the value of inductance L per conductor of an unsymmetrically spaced 3-phase overhead transmission line contains an imaginary term.
Statement (II): The presence of the imaginary term is due to the mutual inductance between the phase conductors and can be eliminated by symmetrically transposing the three line-conductors along the length of the line.
  • a)
    Statement (I) and Statement (II) are individually true and statement (II) is the correct explanation of statement (II)
  • b)
    Statement (I) and Statement (II) are individually true but statement (II) is not the correct explanation of statement (I)
  • c)
    Statement (I) is true but statement (II) is false
  • d)
    Statement (I) is false but statement (II) is true
Correct answer is option 'A'. Can you explain this answer?

Consider a 3-ɸ line with conductors A, B, and C; each of radius r metres. Let the spacing between them be d1, d2 and d3 and the current flowing through them be IA, IB and IC respectively.
The inductances for the above arrangements are given by,

Thus we see that when the conductors of a 3-phase transmission line are not equidistant from each other, i.e., unsymmetrically spaced, the flux linkages and inductances of various phases are different which cause unequal voltage drops in the three phases and transfer of power between phases (represented by imaginary terms of the expression for inductances) due to mutual inductances even if the currents in the conductors are balanced.
The unbalancing effect on account of irregular spac­ing of conductors is avoided by the transposition of conduc­tors, as shown in the figure.
The effect of transposition is that each conduc­tor has the same average inductance, which is given as:

Therefore, Statement (I) and Statement (II) are individually true and statement (II) is the correct explanation of statement (II)
