DNV Obtains Accreditations by A2LA for Power Quality Testing on Wind Turbines (USA)


A2LA’s accreditation for power quality testing of wind turbines is in accordance with ISO/IEC 17025:2005 for power quality testing per the IEC 61400-21 power quality testing standard for wind turbines.

Only a handful of organizations worldwide have achieved accreditation in this area; DNV is the only private company in the U.S. to have successfully completed this evaluation process.

This new accredited service supplements the accredited wind turbine power performance, acoustic noise, and mechanical loads testing already being conducted and allows DNV to perform all of the testing required for type certification.

“Our fulfillment of the requirements of ISO/IEC 17025:2005 means that we meet both the technical competence requirements and management system requirements that are necessary to consistently deliver technically valid test and measurement results,” said John Lyons, DNV’s manager of Accredited Services in North America.

“This represents a long-term commitment to providing the global wind industry with value through a combination of quality service and technical depth,” said Robert Poore, Vice President, Business and Service Development. “We plan to pursue additional accreditation in areas relevant to our work.”

DNV has equipment and trained personnel ready to rapidly deploy to a test site for making power quality measurements. DNV has provided testing services on more than 200 turbines in the last five years in North America, Brazil, India, China, Australia, Korea and other locations. In addition to its four areas of accredited testing (turbine power performance, mechanical loads, acoustic noise measurements, and now power quality), DNV’s testing capabilities also include met tower equipment procurement and installation, custom boom design, special turbine measurements, and other measurement and testing services.
