Abstract: Polymeric insulation is being widely used in HVDC cables owing to its several advantages. The performance of a HVDC cable during transients, such as sudden switching and polarity reversal etc., will not be the same as in steady state. In this work the design performance of a HVDC cable has been evaluated. During transient periods the cable insulation suffers from high electro-thermal stress. In this paper, an electro-thermal model has been considered for simulation. The nonlinear DC conductivity is experimentally measured and incorporated in the model to analyze exact performance of cable as per CigrĂ© standard TB 496. The electric field, temperature distribution and insulation leakage current have been analyzed. Peak electric field and field enhancement factors are obtained.
