Kurzbeschreibung (Abstract)
Due to the development of High Voltage Direct Current (HVDC) cable systems for voltages of up to 525 kV and more, the importance of space charge tests has increased in recent years. Many cable manufacturers have already inte-grated the determination of the space charge distribution into their prequalification (PQ) test procedure [1]. Next to the cables themselves, their accessories are of particular importance. Cable joints are considered as the most error-prone part of cable systems [2]. One approach to mitigate their rate of failure is the use of materials which are specifically designed for HVDC application. The general objective is to reach an improvement of their internal electric, thermal and mechanical performance. A promising way is to introduce nanofillers into the polymer matrix, obtaining a space charge suppression. This paper gives an overview for the possibilities to assess space charges within materials and provides basic criteria to evaluate their space charge behavior under varying additive concentration. In section 6, these criteria are applied on silicone elastomers filled with carbon black nanofillers exemplarily.
