Extracted text: Q1: A 3-phase of sequence ABC transmission line has a conductors of cross section area (82 mm?) and a diameter of (1 cm) as shown in figure below. Delivers a load of 15 MW at 30 kV and power factor of 0.78. Determine the efficiency and voltage regulation of the line. If the line length (65km). The line is completely transposed. For the copper p = 1/58 per meter length. 3 m 4 m 6 m 4 3 m
