Cover Story: Power converters in wind turbines exhibit frequent failures—the causes of which have remained unexplained for years. Pronounced seasonal failure patterns point to environmental influences, in particular to humidity, as a critical stressor and likely driver of converter failure. This paper summarizes the results of field-measurement campaigns in 31 wind turbines of seven different manufacturers spread over three continents. The temperature and humidity conditions inside the converter cabinets are characterized, related to the environmental conditions and the operation of the turbines. Their analysis reveals remarkable relations with the failure behavior. View this paper.
