2GW Britain-France H. V. D. C. Link Transition Joint - Transient Stresses

The maximum values of stress in the joint have been determined for surges and sudden changes in applied voltage and are within the specification for the materials. In the treatment of long term transients arising from polarity reversals the polarization characteristics of the various materials are included. No change in the stress distributions for both 4h and 24h polarity reversals is found after the first six reversals for the Voltalit gas region and after the first three for the paper/oil region.
