Morshuis, P.H.F. (author), Bodega, R. (author), Fabiani, D. (author), Montanari, G.C. (author), Dissado, L.A. (author), Smit, J.J. (author)Interfaces between dielectrics are considered one of the weakest parts of an insulation system but their behavior under electrical stress is not yet completely understood. In particular, when a dc voltage is applied, the electric field distribution at the interface is quite difficult to predict. This is mainly due to the accumulation of internal...conference paper 2007

Calculation and measurement of space charge in MV-size xxtruded cables systems under load conditionsMorshuis, P.H.F. (author), Bodega, R. (author), Fabiani, D. (author), Montanari, G.C. (author), Dissado, L.A. (author), Smit, J.J. (author)A load current in dc high voltage cables results in a temperature drop across the insulation and hence a radial distribution of the insulation conductivity is found. Direct consequence is an accumulation of space charge in the bulk of the nsulation, that may significantly affect its reliability. This phenomenon was modeled in terms of the...conference paper 2007
