Dependence of XLPE insulated power cable wave propagation characteristics on design parameters
TL;DR: In this paper, the relative contributions of the conductors, insulation and semi-conducting screens to the propagation characteristics of the cable are studied by a developed "approximate" model providing analytical expressions that can quantify the contributions to the losses by the different parts of the conductor and dielectric system.
Integration of online partial discharge monitoring and defect location in medium-voltage cable networks
TL;DR: It is shown that the characteristic impedance and propagation velocity of single-core and three-core XLPE cables can be calculated using information available from the cable specifications, and a major part of an incoming pulse reflects on a large RMU/substation with many connected cables.

Jakob Rhyner,M.G. Bou-Diab +1 more
TL;DR: In this article, a one-dimensional model for field control in cable terminations is analyzed mathematically both for linear and nonlinear field grading materials, and the results show that conclusions for non-linear field control based on linear calculations in general are misleading.
