A device for internal fault current control in the end winding region of the stator (2) in a rotating high-voltage electric machine is inserted in the end winding region. The device consists of conducting material connected to ground. Arcs occurring at breakdown of the winding insulation are deflected to ground via this device.
La présente invention concerne un dispositif permettant de réguler de façon interne les courants de défaut dans la zone d'enroulement terminale du stator (2) d'une machine électrique tournante à haute tension. Le dispositif, qui est inséré dans la zone d'enroulement terminale, est composé d'un matériau conducteur relié à la terre. Ce dispositif permet de dévier vers la terre les arcs qui se produisent lors du claquage de l'isolant de l'enroulement.
