Abstract
During the operation of an HVDC cable in an offshore long-distance power transmission mode, the insulation on the cable’s accessories could age and degrade if they absorbed moisture from the surrounding air, such as the diffusion caused by rain or fog condensation. Surface characteristics of water-diffused insulating materials should be studied since the degradation commences there. Surface potential measurements are employed to characterise the surface of water-diffused Al–epoxy nanocomposites, and these nanocomposites are compared to their unaged counterparts to provide a reference for surface characterisation. The diffusion coefficients of aged nanocomposites were found to decrease experimentally with the controlled addition of nanofiller. In spite of the fact that water diffusion nanocomposites have substantially reduced the surface potential characteristics, the incorporation of nanofillers has been shown to slightly improve these characteristics.
