Abstract
The invention relates to a system and a method for monitoring a flange connection of a wind turbine, and to a corresponding wind turbine. According to the invention, one or more monitoring bodies () are mounted on one or more bolt nuts () and/or bolt heads of at least one flange connection of a wind turbine, and a circuit of the monitoring bodies () is produced with connecting cables () such that, upon rotation of a slackening bolt nut () or of a bolt head of a slackening bolt and of the monitoring body () mounted thereon, at least one connecting cable () connected to the concomitantly rotating monitoring body () becomes detached, owing to increasing tensile stress on the connecting cable (), a fault in the flange connection being signaled upon slackening of a bolt nut () or bolt.
