High voltage services of LABELEC to wind energy industry
The high voltage laboratory LABELEC has been servicing wind energy industry for more than 15 years. From the TR 61400 to the latest update of the IEC 61400-24. LABELEC offers high voltage and high current tests for the lightning protection system of wind turbines. These include lightning attachment tests of blades and other components such air terminals of the nacelle. We have experience in high current test to blade receptors, connection components, down conductors, spark gaps and simulation of lightning currents to blades and carbon reinforced plastic materials. Electrical current tests also include current distribution in full scale blades and nacelles. We offer dielectric and electrical conductivity characterization of composite materials. LABELEC facilities also include aging/conditioning chambers to simulate the environmental effects of lightning protection system components.
Risk assessment and root cause analysis
DENA offers risk assessment evaluation of lightning exposure of wind turbines based on lighting occurrence using LINET lightning detection data (GL certified). When lightning problems happen, DENA offers support to the root cause analysis providing the lightning occurrence related to the event.
