4.14 Electromagnetic compatibility (EMC)
4.14.1 Interference caused by electromagnetic elds (EMF)
Description
Fluctuating currents and voltages generate electromagnetic elds (EMF). Electromagnetic
elds can interfere with the operation of electrical devices.
Equipment that generate electromagnetic elds are called sources of interference. Sources of
interference are converters that have not been correctly installed, for example. On the other
hand, interference sinks are devices that are disturbed by electromagnetic elds, e.g. mobile
telephones.
The type of transmission is another distinguishing feature of interference. A source of
interference either transmits the interference to the sink through conduction or through
radiation.
4.14.2 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.
