Abstract
Due to many advantages, many of the current and future power lines are planned to be High voltage direct current (HVDC) cables with extruded (XLPE) insulation. Nevertheless, in HVDC insulation systems the presence of space charges can lead to an increased electric field stress up to the failure of the device. Due to this challenge, it is significant to develop new insulating materials that are suitable especially for HVDC applications. One promising approach is to introduce nanofillers into the polymer matrix for space charge suppression. The weakest points in a cable system are always the cable joints. Just very little has been published on the materials used for cable joints, like silicone rubber (LSR). Nowadays the most commonly used technique for space charge measurement is the Pulsed Electroacoustic method (PEA) [1]. The purpose of this paper is to present a novel PEA setup optimized for the investigation of silicone rubbers that allows applying different temperature gradients across the sample, which are always present in a real cable joint. Additionally, the goal is to investigate the influence of nanoscale Carbon Black (CB) on the space charge behaviour for different filler concentrations and to compare it with the results from Thermally Stimulated Currents (TSC).
