11.2 Electromagnetic compatibility.
Implications for transport.
New European guidelines for Electromagnetic Compatibility.
Electromagnetic compatibility means the ability of an electrical or electronic device in an
electromagnetic environment to function flawlessly., Without the environment there,
beyond certain limits to disrupt and influence.
In the examination of electrical influences caused by the use of an electric device
performance, or to interact with these, a distinction is made between the sources of
interference and the interference inhibitor.
A source of interference is a cause (transmitter) of electromagnetic interference, which in
turn is directly emitted or transmitted to its environment through cables. For example, a
source of interference may be for example a switched induction in a protection, an
electrical device (frequency converter) or a lightning strike. A fault sensor participates in
a part of the energy and is thereby disturbed or even damaged. Many electronic devices
are both sources of interference as interference inhibitor.
EMC regulations and standards specified maximum noise levels at which an electronic
device as a source of interference in the application and use in a particular environment
or which may not exceed the unit during installation.
From 01.01.1996, all in circulation or decommissioned plants to meet the EMC Directive
are marked with the EC Conformity CE Mark. Basis of the Declaration of Conformity EMC
measurement protocols that are part of the quality assurance system should be
established. They must prove that the product or the product alternative to the
requirements laid down in accordance with the EMC directives. This qualification should
be after any modification of the product again to be substantiated. In order to achieve
the prescribed EMC, is the manufacturer of the equipment required to build or apply
blocking filters.
Installers, cabinet makers and users should have systems in accordance with EMC
requirements planned and implemented. Unavoidable disturbance energy must be routed
directly to ground. Links should be avoided wherever possible.
Modern electronics devices work with voltage and low frequency pulses. The EMC directly
consider saving costs. The timely adoption of decoupling measures is therefore
important, while in the planning stage disregarded measures fail to repair.
It is therefore important for the construction of a device or installation a concept to which
criteria are defined and the criteria for substantive values.
These are just some general recommendations that should be recorded. Performing
references in the respective electrical standards and regulations can be found.
