Abstract :
A Finite Element (F.E.) model has been constructed for a 15 kV medium voltage power cable. The model has been used to investigate several areas of importance, not solvable using analytical techniques. The power of this approach is illustrated by three examples: a) the enhancement of electrical stress caused by a deformation at the inner semi-conducting electrode, b) the effect of thermally induced changes within the insulation, c) the effect of water ingress. A distinct shape dependence due to material deformation is shown. The effect of the combinations of water, temperature and material protrusions on the electrical behaviour of the cable is also shown
