Abstract
An electric insulation arrangement including a field grading material including a matrix including a dielectric material. A plurality of micro varistor particles is distributed in the matrix. A plurality of bridge particles include an electrically conducting material and form electrically conducting bridges between individual micro varistor particles. The bridge particles form a percolating network together with the micro particles but do not form a percolating network by interconnection between themselves.
