method and system for evaluating a wind turbine lightning arrester system comprising a plurality of blades made of a carbon fiber reinforced composite

摘要

evaluation method for a lightning turbine (p) lightning arrester system, the lightning arrester system comprising a grounded downconductor connected to each blade (p) by means of conductive plates (1, 2) inserted into the blade (p) corresponding. The method is configured to determine the quality of the connections between the conductor plates (1, 2) and their blade (p), and comprises injecting a direct current (i) between two conductor plates (1, 2) of the same blade (p). ), generating a current flow through the blade section (p) comprised between both conductor plates (1, 2), measuring the electrical voltage (v) at measuring points (pm) of said section, comparing the voltages between them (v), and determine the quality of the connections between said conductive plates (1, 2) and said shovel (p) as a function of the result of said comparison. associated evaluation system.
