Diversion using the lightning rod, lightning with lightning network lightning current along to deflectors safely into the earth, to prevent the lightning directly hit the buildings and equipment. Shielded metal wires of the computer system of electrical connections, including power cables, communication cables and signal lines are shielded wire or through the metal tube shield, room construction, building steel mesh and other metal materials, so that the engine room to form a shield cage. To prevent external electromagnetic waves (including electromagnetic and electrostatic induction of the lightning) interfere with the engine room equipment.

Equipotential bonding of all metal objects in the engine room, including cable shielding, metal pipes, metal doors and windows, equipment, such as Shell metal components for electrical connection. Grounding in computer network systems, in order to ensure its stable and reliable work to protect the computer network equipment and personal safety, environmental electromagnetic interference and electrostatic hazards, you need a good grounding system. Grounding and equipotential connection.

Electrical electronic equipment to connect the signal line, power line, install the appropriate over-voltage protection, the use of the nonlinear effect, the high pulse voltage on the line filter to protect the equipment will not be over-voltage damage. Main protection device for the zinc oxide varistor resistor, two pole or three pole surge arresters, fast clamping diode combination as needed, to form a complete lightning protection.
