Abstract
A lightning protection system for a wind turbine blade with one or two carbon fiber laminates and one or more down conductors equipotentialized with them by one or more auxiliary cables comprising at least one local lightning current injection area in the carbon fiber laminates associated with one auxiliary cable having secondary cables derived from the auxiliary cable and connected to conductive devices embedded in the carbon fiber laminates which are configured for avoiding overcurrents in the carbon fiber laminates. The invention also provides a lightning protection system for achieving a balanced distribution of currents and voltages between the down conductors and the carbon fiber laminates.
