Muito bem atribuído, tenho muitas vezes ido parar a artigos deste OM
em assuntos de EMC como interferências de PLCs, lâmpadas CFL e LED!<br>
<br>
Um dos melhores videos dele que assisti sobre o assunto pode ser
visto a partir de:<br>

<br>
Nota especial para a sonda que ele mostra, usada para medir o nível
de ruído produzido pelas fontes comutadas das CFL (aplicar-se-á
provavelmente também às de LED).<br>
<br>
Era interessante ir-se fazendo uma tabela sobre as "melhores" e
"piores" sobre o ponto de vista QRM para sabermos o que escolher
para evitar poluir as bandas.<br>

<pre wrap="">IARU EMC Coordinator receives IEC 1906 Award
During the plenary session of CISPR, the IEC 1906 Award was presented
to Thilo Kootz, DL9KCE, who represents IARU at this international
standardization organisation in charge of the protection of radio
reception
CISPR is the Special International Committee on Radio Interference and
was founded in 1934 to set standards for controlling electromagnetic
interference in electrical and electronic devices, and is a part of
the International Electrotechnical Commission (IEC).
The leadership of CISPR found the following words for selecting Thilo
for the award: "For significant contributions in defining the
disturbance models and especially in developing the model for radiated
emission limits in the frequency range below 30 MHz for the
Publication CISPR 16-4-4 “Specification for radio disturbance and
immunity measuring apparatus and methods - Part 4-4: Uncertainties,
statistics and limit modelling - Statistics of complaints and a model
for the calculation of limits for the protection of radio services”.
He contributed to the development of the radio services data base of
the CISPR 31 publication. He also made several technical contributions
for the disturbance model of “Grid Connected Power Converters” devices
and installations and actively contributed to the work of the generic
emission standards."
