“We have now established where the fire started and how to address the issue. The fire started in the Harmonic Filter Cabinet as a result of a loose connection in the electrical system that created an arc flash,” Vestas said in a statement.
The solution
“The solution to this problem has been confirmed by specialists; it involves using a different type of washer on the electrical connections in the Harmonic Filter Cabinet. The solution is in the process of being implemented in the affected turbines, and customers are being informed.”
At the site, the burned nacelle has been replaced and is scheduled to be commissioned next week.
