A three-phase, 50Hz, 50 km transmission line uses 3 conductor bundle conductors per phase. The diameter of each conductor in a bundle is 10 mm and the conductors are placed at the vertices of an equilateral triangle with a side length of 20 cm. The three phase bundles are horizontally placed with a distance between phase A and phase B as 1.2 m and phase B and phase C as 1m. The three phase lines are completely transposed. Calculate the admittance per phase
