Abstract The transmission channels of the lightning electromagnetic impulse are analyzed. Combined with the basic principles of lightning protection zoning,shielding,equipotential bonding,SPD installation and other measures,the practical application of lightning protection zoning and specific protection methods of electronic systems against lightning electromagnetic impulses are discussed.
Key words Lightning electromagnetic impulse protection Lightning protection zoning Shielding Equipotential Surge protective device
