Abstract

A computer simulation method is disclosed for simulating an electrical cable having a stranded conductor surrounded by a conductor shield encased in an insulation jacket and having an interstitial void volume in the region of the conductor injected with a fluid composition comprising at least one dielectric enhancement fluid component so as to at least partially fill the interstitial void volume at an initial time. The simulation method comprises for a selected length of the simulated cable, defining a plurality of radially arranged finite volumes extending the selected length of the simulated cable, and estimating the radial temperature of each finite volume. For a selected time period after the initial time, performing a series of steps at least once and outputting or otherwise using the value of the new concentration for the dielectric enhancement fluid component within each finite volume.
