Abstract
A high voltage stator bar includes a substantially quadrangular conductive element made of a plurality of interwoven strands, and an electric insulation applied around the conductive element. The permittivity at the corners of the electric insulation decreases by less than 60% from an inner insulation zone facing the conductive element towards an outer insulation zone.
