Abstract (en)

[origin: WO9827639A1] A conductor element of a group of conductors (2) on the high voltage winding of a revolving electric machine is integrated for controlling the internal potential. A twisted anti-brush discharge contact electrode of the group of conductors (2) is mounted with no insulation on the conductor element (3), but with a larger cross-section to offset the missing insulation (3) or with an anti-brush discharge device on the conductor element (6), integrated in the group of conductors (2). This groups of conductors (2) is surrounded by an anti-brush discharge device (4) and, immediately thereafter, by a high voltage insulation. The invention is particularly suited to high voltage electric machines.
