The Fraunhofer Institute for Wind Energy and Energy System Technology (IWES) is constructing an oil sensor test stand on its grounds in Bremerhaven, Germany.

As the institute explains, wind turbines are increasingly being equipped with oil sensors to monitor the condition of the gearboxes, and the project aims to provide standardized oil sensing testing for the industry. IWES says the focus of the tests are reliability, accuracy and oil sensor operational capability.

“The operational conditions in gearbox oil-circuits for varying installation environments can be simulated here,” explains Dr. Claus Kupferschmidt, leader of the DegradO project at IWES. “Furthermore, degrees of gearbox oil aging under changing operational conditions and with regard to contaminating pollutants such as wear debris, water and dust can also be simulated.”

IWES expects the oil test stand will be completed in September, at which point the first tests on oil sensors made by various producers will then be carried out.

Too Little, Too Late? U.S. House Approves Wind PTC Extension

The U.S. House of Representatives has passed a tax extenders package that would renew the wind production tax credit (PTC) and about 50 other expired tax breaks through 2014. The wind industry argues the short-term fix is virtually no fix at all.


As Congress Deliberates Tax Extenders, Could A Wind PTC Renewal Be Near?

With a few weeks remaining in the 113th Congress, negotiations - and political posturing - suggest the wind industry will soon learn the fate of the production tax credit.
