3-) A three-phase overhead line of 380 kVer with a length of 250 km will be installed. The conductors have a cross section of 1018 mm² and a diameter of 36 mm. of conductors The roughness factor is 0.8 and the spacing between the conductors is 7 m. Since it is 8-0.95 along the line; a) Corona voltage b) Calculate the total corona loss at the mains voltage according to the Peek and Peterson formulas.
