Abstract :
A simple method of calculating corona loss on a unipolar dc transmission line, without a ground wire, is presented in this paper. The simplification occurs due to the avoidance of double integration involved in Sarma and Janischewskyj´s [1] method and also due to a justifiable linear approximation of the corona current density on the conductor surface for this simple geometry. The computer program has less than 100 statements and the typical computation time involved in plotting a V-I characteristic is less than 4 seconds on an IBM 370/145 computer. The error in the computed results, due to the above simplifications, is less than 1%.
