Abstract : This paper presents an adaptive finite-element iterative method for the analysis of the ionized field around high-voltage bipolar direct-current (HVDC) transmission line conductors without resort to Deutsch’s assumption. Unlike all attempts reported in the literature for the solution of ionized field, the constancy of the conductor’s surface field at the corona onset value is directly implemented in the finite-element formulation. The present paper considers both the unequality of the +ve and – ve ion mobility and onset voltage values. In order to investigate the effectiveness of the proposed method, a laboratory model was built. It has been found that the calculated V-I characteristics and the ground-plane current density agreed well with those measured experimentally. It has been found that taking into account the unequality of +ve and –ve mobility and onset values improved the calculated results towards the experimental values.
