TUTORIAL PROBLEMS 1. Estimate the corona loss for a three-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 air is 30°C and the atmospheric pressure is 750 mm of mercury. Take irregularity factor as 0-85. Ionisation of air may be assumed to take place at a maximum voltage gradient of 30 kV/ [316-8 kW] cm.
