    • A discharge apparatus for a wind turbine enables electric charge to be discharged between a first and a second part of the wind turbine rotatable relative to each other. It has a charge transfer unit electrically connected to the first part, and an electrically conductive slideway electrically connected to the second part. The charge transfer unit has a sliding member made of an electrically insulating material and maintains mechanical contact to the slideway; and a spark-gap electrode electrically connected to the first part and arranged to move in unison with the sliding member over the slideway. The spark- gap electrode and slideway thereby form a spark gap with a spark-gap width controlled. Discharging is enabled by sparks bridging the spark gap, whereas the first and second parts are electrically isolated from each other in the absence of a spark.
