<p>An overhang corona protection device (5) for improving the protection of component against electrical corona discharges comprises: a non-woven substrate made of fibers and configured to be electrically insulating; and a coating containing silicon carbide disposed on the substrate. Independent claims are also included for: (A) an electric machine comprising: a rotor; a stator; and an overhang corona protection device covering a portion of at least one of the rotor and the stator (1), and including a non-woven substrate made of fibers and configured to be electrically insulating, and a coating containing silicon carbide (SiC) disposed on the substrate; and (B) a method for fastening an overhang corona protection device onto an overhang part (11) of a conductor (3) of a stator of an electric machine, comprising: providing a non-woven electrically insulating substrate made of fibers in the form of a tape; impregnating the substrate with a varnish containing SiC grains to form a coating on the substrate; winding the overhang corona protection tape onto the overhang part; and curing the varnish.</p> |
