Bushing for a power system

A bushing for a power system, comprising:

• a conductor, and
• a condenser core,
• wherein the condenser core comprises a dielectric sheet and a plurality of disjoint regions of electrically conducting material provided on the dielectric sheet, wherein the dielectric sheet and the electrically conducting material form a wound structure around the conductor,
• wherein in at least one region of electrically conducting material, the electrically conducting material is a semiconducting material, wherein the semiconducting material extends more than one turn around the conductor, whereby the at least one region of electrically conducting material has overlapping edges in a radial direction, and
• wherein the dielectric sheet-(extends between the overlapping edges whereby a capacitance is formed between the overlapping edges, which capacitance is partly defined by an overlap length of the overlapping edges and which capacitance forms part of a resonance circuit of the at least one region together with an inductance associated with an azimuthal current which in operation of the bushing flows in the azimuth or circumferential direction along the at least one region of electrically conducting material, wherein the overlap length is such that the resonance circuit has a resonance frequency contained in a very fast transient, VFT, spectrum, wherein the resonance frequency is in a range of 0.5 MHz to 10 MHz.
