1. Lejesystem (200) til en vindmølle med en generator med en udvendig rotor, fortrinsvis til en generator med en udvendig rotor til et rotorhus af en vindmølle, hvilket lejesystem (200) omfatter en indvendig lejering (210), en udvendig lejering (230), et første elektrisk isoleringselement (220), et andet elektrisk isoleringselement (240), en flerhed af rulleelementer (250), et første metalelement (261) og et andet metalelement (262), hvor rulleelementerne (250) er anbragt ved en indvendig volumen mellem den indvendige lejering (210) og den udvendige lejering (230), det første elektriske isoleringselement (220) omfatter det første metalelement (261), det andet elektriske isoleringselement (240) omfatter det andet metalelement (262), det første elektriske isoleringselement (220) er anbragt i det mindste delvist rundt om den indvendige lejering (210) for at tilvejebringe en elektrisk afskærmning mod det indre af lejesystemet (200), og det andet elektriske isoleringselement (240) er anbragt i det mindste delvist rundt om den udvendige lejering (230) for at tilvejebringe en elektrisk afskærmning mod det indre af lejesystemet (200).
2. Lejesystem (200) ifølge det foregående krav 1, hvor det første metalelement (261) er anbragt på den ene side af det første elektriske isoleringselement (220), og det andet metalelement (262) er anbragt på den ene side af det andet elektriske isoleringselement (240).
3. Lejesystem (200) ifølge det foregående krav 2, yderligere omfattende et tredje metalelement (263) og/eller et fjerde metalelement (264), hvor det første metalelement (261) og det tredje metalelement (263) er anbragt på modstående sider af det første elektriske isoleringselement (220), og det andet metalelement (262) og det fjerde metalelement (264) er anbragt på modstående sider af det andet elektriske isoleringselement (240).
