Electromagnetic compatibility and CE mark |
|
Electrical
installations, systems and devices which are to be marketed within
the EC must
be given the CE mark of conformity by the manufacturer or the
importer.
The products
must be tested to ensure that they satisfy the requirements of the
law relating to Electromagnetic
Compatibility (EMC).
The standards of the EMC law classify the
permissible degree
of electromagnetic interference emission as well as immunity to it.

EN61000-3-2 Harmonics analysis |
|
The permissible limit
values and measuring methods are laid down in the standard
EN61000-3-2.
There are 4 device classes (A, B, C, D), for which different
evaluation methods and limit
values apply. Below is the table for classifying devices according
to EN61000-3-2/A14.
For EN61000-3-2 an other classifying is used. The power
measuring
devices from the LMG series (LMG95 and
LMG450) can carry out an
evaluation of compliance
with the standard according to the relevant device class.
|
| Class A |
- Balanced three-phase equipment
- Household appliances except equipment
identified as Class D
- Tools excluding portable tools
- Dimmers for incandescent lamps
- Audio equipment
|
| Class B |
|
| Class C |
|
| Class D |
- Equipment having a specified power
according less than or equal to 600W, of the following
types:
- Personal computers and personal
computer monitors
- Television receivers

EN61000-3-3 Flicker and voltage changes |
|
Flicker is determined by
the amplitude and frequency of line voltage fluctuations.
Voltage fluctuations in turn occur in the mains network impedance
through the repeated
sudden current variations of a consumer.
