With the continuous expansion of the number and scale of electronic equipment in industrial control system, electronic equipment generally has the weakness of low insulation strength and poor overvoltage tolerance. When it is attacked by lightning electromagnetic pulse, especially lightning electromagnetic pulse, it will have different degrees of operation failure, Therefore, the lightning protection measures of multi-level shunt (no less than three-level lightning protection) should be taken for the electronic equipment in industrial buildings to ensure the safe and stable operation of production equipment.
