Electromagnetic compatibility (EMC) is an equipment characteristic or property and is defined as " the ability of equipment or a system to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbances to anything in that environment " (IEV 161-01-07).
The compatibility level for an electromagnetic disturbance is a reference value used to compare equipment emission and immunity. From the compatibility level, an emission limit and an immunity limit are defined. The immunity limit is higher than or equal to the compatibility level.
This research is crucial for ensuring electromagnetic compatibility (EMC), evaluating electromagnetic interference issues, optimizing machine design, and complying with EMC standards.
To provide a framework for testing and improving equipment, the concept of compatibility level is introduced. The compatibility level for an electromagnetic disturbance is a reference value used to compare equipment emission and immunity. From the compatibility level, an emission limit and an immunity limit are defined.
There is a capacitance between any two conductors separated by a dielectric (air and vacuum are dielectrics, as well as all solid or liquid insulators). If there is a change of voltage on one conductor there will be change of charge on the other, and a displacement current will flow in the dielectric.
The value of these margins is not important in itself, as the compatibility level is just a predefined level used to fix emission and immunity limits. Of more importance for achieving EMC is the compatibility margin, the ratio between the immunity limit and the emission limit.
