Question

In a 250 km long, interphase voltage of 154 kV, 50 Hz three-phase transmission line, the diameter of steel core aluminum conductors is 22 mm, the roughness coefficient of the conductors is 0.8, and the spacing between phases is 4 m. Average air temperature along the line is 27 degrees, air pressure is 750 mmHg. Calculate the total corona loss per phase at 1.5 times the operating voltage under these conditions (E0=21.2 kV/cm)
