Now you could certainly idealize the transmission line for the
purposes of a standard test, and you would need to, but if you do that,
why not specify and measure the BPL

Hi all,
We are currently designing an appliance for the gaming industry and looking
for a suitable PSU. It appears that a lot of PSU’s are assessed against EN
60950 especially those for the PC industry. We have a couple of such PSU’s
in mind with ‘SELV’ outputs but under EN 60335 there is a

I am looking for reliability information on high intensity LED

1. Some vendors are supplying devices which seem like they contain a
bare die on ceramic substrate. Is there any encapsulation there or maybe
it is not required?
2. Is there a good basis for estimating life? We

He/she will need to choose one or the other. As long as that choice is
available and not forced by other BPL users driving noise into his/her

I don't know what the originating post was, I came into it when the question
was about how to define/determine the far field of an antenna.
Relative to the larger question, about how to control BPL leakage so as not
interfere with licensed users of the HF/shortwave band, I offer the
following
Correct me if I'm wrong, but the subject of the original post is the field
strength versus distance for BPL leakage from 1 - 30 MHz.
I set up a simplified NEC-2 model of a house with wiring and began to
measure the field strength from 1 to 30 MHz at distances from 10 to 100
meters. This proved
It is indeed Fischer Custom Communications at:

They do have these coupling clamps. The founder, Joe Fischer, was friends
or colleagues with Mr. Balint Szentkuti, who wrote several papers back in
the 1980s about replacing radiated OATS measurements with common mode

John and Ken,
Isn't this one of the main reasons that it's better to measure the
emissions from a line with a coupling clamp at these frequencies (1 to
30 MHZ).???
Yes. Or a current
As I noted in the previous post, I don't know very much about BPL. I
surmise that the home electrical mains serve as a transmission line for the
BPL signal. However, whereas the home mains system distributes mains power
(50/60 Hz) differentially, I assume that the BPL signal is sent over the

There is a company that makes coupling clamps...and their name escapes me
