Abstract (en)
[origin: WO2014207047A1] The invention relates to a device for diverting earth currents, more particularly in wind turbines, from electrical machines, comprising an earthing ring mounted on a rotor of the electrical machine and a sliding contact which is connected to earth and is in contact with the earthing ring. The sliding contact element has a carbon brush with an apparent density between 1.1 and 1.4 g/cm³, and the carbon brush contains a metal insert made of silver, the silver content being between 1 and 8%.
