2.6. Transmission Line
Different lengths of overhead lines and cables have been used to investigate the impact of transmission line (overhead lines and underground cables) energization. In terms of overhead lines, the lengths that have been undertaken are 50, 100, 150 and 200km lines. For underground cables, the lengths that have been undertaken are 10, 20, 30 and 40km. Fig. 5 shows the 132kV transmission line parameters used in this study.
