Siemens Gamesa Renewable Energy and Iberdrola have begun field-testing blade-scanning technology developed by Spanish start-up Das-Nano. The company says the system can be used to scan a blade of grass or other plant material for signs of disease. Das-Nano said Notus was less destructive and more precise than the traditional pull-off inspection method, and at less than €100,000 ($111,860) per machine, was more cost-effective. Nordex, Suzlon and Vestas are also mulling testing the technology.
Siemens Gamesa Renewable Energy and Iberdrola have begun field-testing blade-scanning technology developed by Spanish start-up Das-Nano. Named Notus, the system uses terahertz imaging to assess the condition of the different layers of a wind turbine blade coating and detect faults.
