Electromagnetic compatibility (EMC)
4.7.1
Interference caused by electromagnetic fields
Description
Fluctuating currents and voltages generate electromagnetic fields. Electromagnetic fields can
interfere with the operation of electrical devices.
Equipment that generates electromagnetic fields is called a source of interference. Sources of
interference may be converters that have not been correctly installed, for example. On the
other hand, interference sinks are devices that are disturbed by electromagnetic fields, e.g.
mobile telephones.
The type of transmission is another distinguishing feature of interference. A source of
interference transmits the interference to the sink either through conduction or through
radiation.
4.7.2
Electromagnetic compatibility (EMC)
Description
Interference suppression measures increase the electromagnetic compatibility (EMC).
EMC interference suppression measures allow the device to function correctly. As a
consequence, the device is neither a source of interference for other devices nor an
interference sink that can be disturbed by other devices.
