Abstract

A method for the simulation of dynamic carrier injection and motion in cross-linked polyethylene (XLPE) insulation systems is presented. In a first study the influence of a cylindrical 50-μm conducting impurity on the surface of the conducting layer is investigated. For the simulation of the dynamic space charge formation and motion in the high-voltage cable under investigation the influence of a lightning impulse is considered. The simulation shows the penetration and storage of charge carriers in a region around the impurity. In the example presented the amount of injected charge around the impurity does not reduce the expected maximum field strength significantly in the phase of high-voltage stress
