Estimate the corona loss for a 3-phase, 110 kV, 50 Hz, 150-km-long transmission line consisting of three conductors, each of 10 mm diameter and spaced 2.5 m apart in an equilateral triangle formation. The temperature of the air is 30oC and the atmospheric pressure is 750 mm of mercury. Take the irregularity factor as 0.85. Ionisation of the air may be assumed to take place at a max voltage gradient of 30 kV/cm.
