Blitzeinschlag in Windrad

Lightning Strikes on Wind Turbine Scotland: Wind turbines are lightning magnets—and strikes on these tall, spinning structures can cause significant damage. Blades explode; generators and control system electronics fry. To figure out how to safely disperse lightning, turbine manufacturers have turned to the Technical University of Denmark's High Voltage Lab. Using giant versions of standard electrical devices such as sphere gaps, transformers and capacitors, the facility can generate huge arcs of electricity—up to 800,000 volts AC. The equipment helps companies test how new turbine parts or mechanisms will respond to electrical surges out in the field.

“Many high-voltage labs, they look like something from the 1960s,” says Joachim Holbøll, a professor and deputy head of the university's Center for Electric Power and Energy. “But we are doing necessary stuff in there with the newest equipment. Parts of this will always look a little old-fashioned, but that is simply because it works.”
