Electromagnetic compatibility (EMC)
as a prerequisite for efficiency and safety
The tremendous growth in the electrification of our everyday life is proceeding at an apparently unstoppable pace. This is a development that can also have unwelcome effects on sensitive electronic systems, since the applicable norms for effective screening from electromagnetic radiation are lagging behind technical developments. It is even more important for possible risks to be spotted in good time and correctly assessed.
Risks when operating electronic devices
In areas of intensive activity, such as hospitals or laboratories, military installations or in industry, many electronic systems are in use for diagnosis, monitoring, treatment etc. Electromagnetically-occasioned influences from inside or out can lead to considerable interference and have unfortunate consequences.
Risks during data processing
An unexpected problem occurring during electronic data processing or a time-consuming malfunction of a computer network are regrettably nothing unusual. These interfering fields are to an increasing extent responsible for these.
Risks for data security
Everywhere that sensitive data is being processed, data security must be to the fore, since, even with a relatively small amount of effort, whole IT systems can be deliberately destroyed by external influences. In order to make access without permission to sensitive data by unauthorized persons impossible, suitable measures should be taken, since even without cable connection, a lot of data can be viewed on computer screens, graphics and video cards at a distance of up to about 100 metres, by using appropriate means.
An electronic system complies with EMC (electromagnetic compatibility) directives, if: |
- |
the electromagnetic radiation it generates does not interfere with its own
system
|
- |
the electromagnetic radiation it generates does not interfere with other
electronic systems |
- |
other electronic systems' operation cannot be disturbed |
