Time Domain simulation of PD Propagation in XLPE Cables Considering Frequency Dependent Parameters

Partial discharge (PD) detection and location is of great significance for the power cable insulation condition monitoring, where analysis of the PD propagation is needed. This paper presents the single-core model of cross-linked polyethylene (XLPE) cable considering the influence of skin effect and semi-conducting screens. To analysis the propagation of PD pulse in time domain, the model firstly is rational approximated using vector fitting method. Based on the fitting results, the π section lumped parameters model is then proposed. Examples on two cables with different permittivity approximating forms of semiconducting screens are presented.
