ABSTRACT
Electromagnetic compatibility (EMC) has become an essential parameter to be taken into account in an industrial project involving signal or power electronics. This article details the principal phenomena of natural and artificial electromagnetic perturbances such as lighting strikes, electrostatic discharges or industrial activities. Analysis processes of the EMS are also described; they are analysis carried out on each system composing the installation by means of the determination of several parameters including the level of perturbances emitted, the immunity level and attenuation.

INTRODUCTION
This article provides an introduction to electromagnetic compatibility (EMC). After presenting the notions of electromagnetic environment and compatibility, the main phenomena of natural and artificial electromagnetic disturbances are described, giving a few examples and considering the coupling of emitted disturbances (conducted and radiated) to their "victims". Until very recently, EMC has been approached from an experimental, even empirical angle, and it is now becoming necessary to predict EMC effects in equipment or systems by calculation. A few significant examples and some thoughts on simulation tools will help illustrate the methodologies specific to the EMC field.
This article is the first in a series dedicated to studying the various facets of this vast field, which concerns all low- and high-power electrical and electronic devices and systems, over a frequency range from a few hertz to a few tens of gigahertz (GHz). A number of articles are offered, based on the following general items:
EMC measurements and standards ;
transmission of conducted and radiated disturbances ;
electromagnetic (EM) effects of lightning ;
EMC in the field of high currents ;
EMC of electronic boards ;
methods and tools for conducted and radiated EMC simulations, from subsystems to complex systems ;
means of reducing electromagnetic interferences: filtering, shielding.

Standards
Standards and normative documents are available in France from AFNOR for non-electrical documents, and from AFNOR for electrical documents translated into French. For documents concerning electricity and therefore electromagnetic compatibility, international documents are available from UTE. They are in French (left-hand page) and English (right-hand page) for IEC and CISPR documents. Both languages carry the same weight. The...
