  4. 2. Modelling electrical properties of composite materials

    Author : Eva Mårtensson; KTH; []
    Keywords : ;

    Abstract : Composite field grading materials are used to avoid stressconcentrations in high voltage applications such as cableaccessories and generator or motor end windings. The compositematerials consist of an insulating matrix filled with suitableconducting or semi-conducting particles. Silicon carbide (SiC)powder is one such filler that is being employed. READ MORE
