abstract = "This paper presents space charge accumulation characteristics of cable grade and capacitor grade nanostructured polypropylene (PP) materials, providing initial results regarding the electrical properties of nanofilled PP materials belonging to the European project GRIDABLE. This project has the aim to develop DC cable extruded insulation and MV and LV DC capacitor films having enhanced performance with respect to presently used materials. The paper shows that nanostructuration may be beneficial, especially at higher temperature, to improve the capacitor-grade material performance. On the other hand, this work validates the importance of surface functionalization of nanofillers, leading to lower space charge accumulation on DC cable-grade materials.",

INTRODUCTION The trend towards more environmentally compatible electrical technologies is growing the investments in DC electrical apparatus and relevant insulation systems. Focus is, recently, on thermoplastic, thus recyclable, materials. Higher operating electric fields and temperatures would be needed to increase space factor in electrical apparatus design and efficiency, besides specific power. This, however, will involve improving short term and long term performance of the insulating materials which can be used for DC applications. A new European project called GRIDABLE (Polymer Nanocomposite Insulation Material Enabling Integration of Renewables and DC Storage Technologies in the AC Energy Grid) was launched recently under the HORIZON 2020 framework funded by the European Community. Various partners,fromuniversitiesandresearchinstitutionstocableand Funding Information: VII.ACKNOWLEDGMENT GRIDABLE is a consortium consistingof3industrial partners(GEGridSolutions,NexansandTerichemTervakoski), 1 consulting company (InnoEXC), 1 research institute (VTT) and 3 universities (University of Bologna,Universityof Tampere and University of Twente).
