The typical structure of the combined lightning arrester is an N-PE structure. Compared with a single structure lightning arrester, this lightning arrester combines the advantages of two different products and reduces the disadvantages of a single device. Advantages: large flow rate and fast response time Disadvantages: relatively high residual pressure Engineering application: The lightning protection device used only in the N-PE system is suitable for use in areas with large voltage fluctuations.
