4. Earth and weights

4.1 General

When it comes to solving electromagnetic compatibility problems, the notions of grounding networks, mechanical grounding, electronic grounding, meshed grounding networks, star ground wiring, equipotentiality, grounding of cable shields and racks, etc., systematically come up like leitmotifs.

We're going to take a look at the whys and wherefores of connecting electronic equipment to the grounding network. The first step will be to define the ground network and the various possible ground networks, then the role of the ground network, the physical phenomena involved, and finally to give recommendations for industrial installations.
