High voltage system In a three phase 500 kV transmission line, diameter of the conductors are 48 mm. The breakdown strength of airunder standard atmospheric conditions (in which pressure is 760 mm Hg and the temperature is 200C) is 30 kV/cmWe install this transmission line in a region with different atmospheric conditions in which air pressure is705 mm Hg and the temperature is 50 °C, determine the minimum distance between two phases if the correctionfactor is k=0.92.
