The Viöl Training Center of the independent maintenance company Deutsche Windtechnik offers individual training courses with a focus on plant technology. The training courses take place under unique conditions. The knowledge is imparted to the participants on original turbines from the manufacturers Vestas, NEG Micon, Siemens, Enercon and Senvion in a realistic way. The permanently installed nacelles represent almost the entire spectrum of technology that service technicians find in their daily work. Here, troubleshooting can be carried out simultaneously at a training location, and practice-relevant questions of electrical engineering, mechanics and hydraulics, control and operation can be clarified. The training concept includes both basic teaching and subject-specific training.
