Abstract
The invention relates to a method and an arrangement for avoiding stray currents in a wind power plant. There is an insulating power source having a galvanic decoupled secondary side, an electrical load coupled to the secondary side of the insulating power source through an electrical conductor and a stray current sensitive mechanical component of the wind power plant. The insulating power source is located at a first side of the stray current sensitive mechanical component and the load is located at a second side of the stray sensitive mechanical component. The electrical conductor is coupled to a common ground potential at the second side.
