Abstract
In a lightning protection system for a wind power generation installation, a conductor ring 16 is provided on a wind mill vane 1 and at a rotor casing 6 incorporating a wind power generator 3 a zinc oxide element 18 is provided so as to face the conductor ring 16 with a spark gap 17, thereby, if a lightning in winter season which causes to flow a large current for a long duration time hits the wind mill vane 1, the wind power generation installation is effectively protected.
