The test method of the thunder and lightning direct effect protection equipment

Abstract In order to avoid the harm caused by direct effect of lightning, modern new ships are equipped with lightning protection devices. However, due harsh environment such as high temperature, humidity and salt, it is easy change its performance indicators affect effect. Taking device gaps installed at rear end ship antenna an example, through study working principle main technical indicators, items that need be tested regularly determined, corresponding test methods formulated. Through a large number experiments data verification, conclusion method can effectively reflect facilities then evaluate drawn. The research results this paper great significance equipment, accurately grasp changes ensure
