A lightning arrester is a device used to protect electrical equipment. When struck by lightning, the lightning arrester can lead the lightning energy to the ground, so as to protect the equipment from being burned. As one of the important accessories of power equipment, arresters are widely used in the market. When purchasing lightning arresters, users need to choose products that suit them according to their needs. Generally speaking, the withstand voltage, rated current, and discharge current of the arrester are all factors that need to be considered. At the same time, it is also necessary to choose different models according to different usage scenarios, such as outdoor lightning arresters and indoor lightning arresters. Some details need to be paid attention to when using lightning arresters. First of all, the arrester must be connected to the grounding facility to function. Secondly, in order to protect the arrester, products that meet national standards should be selected, and the arrester should be inspected and maintained every year. In addition, when struck by lightning, the lightning arrester will release a strong current and sparks, so the electrical equipment should be stopped and the power plug should be unplugged. Finally, since the arrester has a certain life span, it needs to be replaced regularly even if it is not struck by lightning. Overall, the purpose of a surge arrester is to help protect electrical equipment from elements such as the weather. Users can ensure the effective operation of the arrester and prolong its service life by choosing the product that suits them, complying with the usage specifications and performing necessary maintenance.
