Figure 3.7 illustrates two single-phase transmission lines. The Geometrical Mean Radius (GMR) of each conductor is (r^{prime}).
Question:
Figure 3.7 illustrates two single-phase transmission lines. The Geometrical Mean Radius (GMR) of each conductor is \(r^{\prime}\). In Fig. 3.7 (b), conductors " 2 " and " 3 " are for sending power, and conductor " 1 " is for receiving power. What relation should be held between \(D\) and \(r^{\prime}\) so that the inductances of the transmission lines become equal?
1) \(D=\frac{9}{4} r^{\prime}\)
2) \(D=\frac{37}{16} r^{\prime}\)
3) \(D=\frac{5}{2} r^{\prime}\)
4) \(D=\frac{21}{8} r^{\prime}\)
