2. Electromagnetic compatibility
The distributor's network distributes voltage, and customer loads are connected to this voltage.
-
These loads "draw" currents whose shape is more or less proportional to the voltage.
Note :such currents behave like the superposition of a current at the fundamental frequency and currents at other frequencies.
The currents drawn by certain devices can take a variety of forms: fluctuating amplitude, impulses, distortions due to the non-linearity of the circuits supplied, distortion of the three-phase system. Compared with ideal equipment, which would draw a current strictly proportional to the voltage, these current distortions can be likened to the emission of disturbances from the load to the network. When the currents representing the disturbance...
