Re: Camera on Power-Line Adapters

Hey Ed,

This is some follow up information with the camera issue being
effected by the EMI or RFI lighting at the sign.

I decided to try the Ferrite Cores first before the electrician changed
the wiring to dedicate or split with wiring feed.

I had purchased a set of 20 ea Split Ferrite Cores of various sizes.

Kind of a long story but I kept adding the Ferrite Cores to the hot and
neutral wires feed the sign lights.  First attempt was a total of 2 per
wire.  It had no effect.  Then added 2 more per wire.  No effect.

I was turning on the sign lighting on to check and then off again.

Then again added 1 of the largest size per wire and SUCCESS!!!.

Then just for a little extra bonus I added 1 more of the largest size
per wire.  These larger cores had a inside diameter of maybe 3/8" to 7/16".

At this point I was a VERY HAPPY CAMPER!!!!  Then at 5:03 PM the lights
turned on for the evening.  And the camera turned off.  #*@(&$^#%*@**(#

I returned this morning and started adding some of the smaller cores.
Inside diameter about 1/8".  After adding 2 ea to hot and neutral and
turning on the sign lights, all was good.  I then added another 2 ea
per wire and left the sign on for the day.  For now all looks good.

So I now have a total of 9 each on hot and neutral.  If it stays good
I am again a HAPPY CAMPER!!!

My questions:

Do you know, how does the size of the Ferrite Core work into this
blocking of EMI or RFI for something like this??

Is there a relationship between the inside diameter and the thickness of
Ferrite that plays a role in the effectiveness with size of wire??

Is there a relationship in the length that has a greater effect??

Maybe you don't know the answers to the above but, I am now intrigued as
to how this Magic worked for me and I am struggling to understand
exactly how it did.

Either way, a big THANK YOU to you for the suggestion.  I really do
appreciate it.  I would certainly buy you lunch if I knew where you
were and I was close.

Have a great rest of your weekend.
