The total conductor cross section of a 537.40 kV (Peak value) three-phase overhead line with a length of 100 km is 517 mm2 and the conductor diameter is 29.6 mm. The roughness factor of the conductors is 0.8 and the distance between the conductors is 6 m. The ambient pressure along the line is 650 mmHg and the temperature is 15oC. Since there is corona discharge in only 5 km of this line, find the total Corona loss lost to the line using the Peek equation (Ed=30kVpeak/cm for Air). I would be very happy if you could be quick. :)
