The research focuses on the performance analysis of a HVDC cable in relation to the influence of surrounding soil on electro-thermal stresses experienced by the insulation. Different soil thermal properties were simulated under load cycles with polarity reversal based on Cigre standard TB 496, aiming to understand the impact of geographical location on cable installation.
The advent of polymeric cables is believed to be one of the greatest breakthroughs in the field of HVDC power transmission. With time, various problems associated with the polymeric cables came into light. This led to an increased interest in the investigation of the effect of transients rather than the much-explored steady state behavior. In the current work, the authors present a design performance analysis of a HVDC cable exploring the effect of soil surrounding the cable on the electro-thermal stresses experienced by the insulation. The cable has been simulated for different soil thermal properties, under Cigre standard TB 496 based load cycle with polarity reversal, to get a better understanding of the effect of the geographical location of installation of the cable.
