Currently, wind turbine blades are equipped with an air-termination system, a type of lightning rod that ... the air-termination at the tip and causing damage. This happens because the positive ...

Lightning is a fact of life for wind farm owners, and one that is increasingly frequent as towers get taller and materials needed to make them change, says turbine blade expert Rosie Barnes. “Each ...

RES announced it has been granted a U.S. patent for a new method of inspecting wind turbine blades. It allows users to ...

Wind turbines are potential targets for lightning strikes. The turbine’s lightning protection system (LPS) is cumbersome and costly to check but needed to prevent blade damage. We have designed an ...

A wind turbine blade tip made using ORNL-developed carbon fiber emerged pristine when tested in a lab against high-voltage jolts of simulated lightning. Disclaimer: AAAS and EurekAlert!

The Berrybank wind project in Victoria has been shut down after an incident which appears to show the collapse of one of its turbines. The project, west of Geelong, features a total of 69 Vestas ...

Knowing a wind turbine blade’s deflection is vital to engineering and validating more efficient blades. We used groundbreaking techniques in GPS systems to track the position and orientation of a ...

Vestas is investigating whether a lightning ... 4.2MW wind turbine in Australia. The turbine at the Berrybank Wind Farm in the state of Victoria collapsed earlier this week. Images from the site show ...

the WTG (wind turbine generator) is fit for service and has redundant power, and post-commissioning, the blade monitoring system is functioning properly and will shut the WTG down if blade damage ...

The full wind blade tip emerged pristine from high-voltage ... manufacturers often decline to cover costs, labeling turbine lightning damage an exempt "Act of God." ...

Erosion is all around us, from the meandering course of rivers and other waterways, to the gradual carving out of channels in even the toughest mountains, and the softening of features in statues.
