Abstract :
Knowledge on how wave propagation characteristics and other parameters depend upon cable design is an important base in establishing diagnostic methods for cable insulation. In this study, a shielded medium voltage XLPE cable is investigated and a high frequency based measurement technique is used to measure the properties of the cable material, particularly the semi-conducting screens, in the frequency range 1 kHz to 1 GHz. A materials model is then developed based upon these measurements and this is incorporated into a model for the whole cable. The results are then compared with those obtained from time domain measurements carried out on the XLPE cable
