Lightning strikes can cause transient overvoltage and current surges fatal to electronic components that are not properly surge protected and grounded. Wind turbines are especially susceptible to lightning strikes considering their height (typically 60 to 100 m) and the fact that they are usually placed well away from other structures to take maximum advantage of wind flow. Tall structures standing alone in the open make great targets for lightning. Switchgear and control circuitry in the tower and nacelle must be protected by ensuring the structure is properly grounded in accordance with IEC 61400-24.
CommScope offers copper-clad steel (CCS) grounding solutions that are excellent for grounding individual turbines and connecting turbines in a wind farm to provide a common ground. CCS costs less than comparable solid copper conductors, and its bimetallic composition (offering little or no scrap value) discourages thieves. CCS products are also durable and provide more tensile strength than solid copper conductors. To see more information about CommScope’s wind power solutions click on the link at left.
