2. Protection against electromagnetic pulse

2.1 Principle

• The usual methods of protection against EMI are based on the following complementary techniques:

  • provide extensive radioelectric shielding for the equipment (Faraday cage concept), to protect against radiated effects and prevent excessive wave penetration inside the equipment;

  • minimize EMI interactions and couplings, i.e. reduce the length of cables and connecting wires, especially those located outside the equipment and therefore directly exposed to the main threat;

  • protect circuit sub-assemblies and electronic components at sensitive points, i.e. the entry points for disturbances in the form of electrical overloads created by EMI...
