Abstract
Existing methods for calculating corona losses on monopolar and bipolar dc transmission lines have resorted to the assumption that the space charge of corona does not affect the direction of the electrostatic field. This assumption was aimed at making the calculations possible. In this report corena loss calculations are made in which this assumption and others are replaced by correlating tlie corona space charge density to the avalanche growth inside the ionization zone at the high voltage conductor. This approach seems to be more realistic, gives better agreement with experiment and needs much less computer time.Keywords
