Abstract
A bearing arrangement to avoid a static charge in a bearing is provided. A bearing arrangement for a wind turbine comprises a first bearing shell that is prepared to be coupled to a first part of the wind turbine. The bearing arrangement comprises a second bearing shell that is prepared to be coupled to a second part of the wind turbine. The first and the second bearing shell are arranged in a way that the first and the second bearing shell are rotatable with respect to each other and have a first isolation ring for electrical isolation, so that the first part of the wind turbine can be rotated with respect to the second part of the wind turbine and avoid static discharge.
