Abstract :
Simplified analytical analysis of ionized fields associated with HVDC transmission lines is possible if it is based on Deutsch´s assumption. The resulting voltage-current (V-I) characteristic may be conveniently used to calculate the power losses of a HVDC transmission line. However, such an approach has been criticized because Deutsch´s assumption is considered invalid for the line-plane geometry. This paper verifies the validity of the V-I characteristic thus obtained by comparing it with numerical results which are generated using a new method developed by the authors, in which Deutsch´s assumption is not employed
