Re: Computer Monitor Flickering
...If I were to deliver to you all the scientific studies done on this in the last 20 years it would take an 18-wheeler, literally. Everyone can have an opinion and reaction, but hopefully after at least getting aquainted with some facts.
Just one citation: the IARC (International Agency on Research on Cancer), of the WHO, after an exhaustive review of the research, concluded in 2001 that a 4mG power-frequency AC magnetic field is associated with childhood leukemia in a causative way...
Karl, that's all well and good but if any of it had any merit there would be regulations in place to deal with the issue like we have for smoking and lead for instance. At this point it's only raw research with lots of speculation and hype and absolutely no smoking gun. Maybe someday there will be proof, but there isn't any now.
My point to all of this is that until there are regulations we as electricians have no business setting ourselves up as self appointed experts on EMF remediation with knowledge we obtained on the internet.
We are not doctors, we are not physicists, we are not scientists. We are electricians whose job is to see that electrical energy is provided to the population in a safe and efficient manner in accordance with the present NEC and local regulations and that's all.
Until the NEC or local regulations require us to deal with EMF's and we have been formally educated on the why's and how it should be done it's not only not our job, but you are misleading your customers.
