Re: LV line filters
Hi Samuel And Coilers,
I got help with this recently and this is what I decided to go with and
it is working well. I ran mine backwards between the NST and the
variac. I drove a eight foot ground rod into the ground outside my
garage and used it specifically for the EMI filter ground only.
My EMI filter came from www.meci-dot-com it is a 37amp corcom
EMI filter, cost me $3.95 surplus. They have a minimum order though
so I got lot's of other goodies too from them.
I also measured 600ohms from this ground rod to the houses common
ground. Not sure what that means, but I thought it was pretty fascinating
at how little resistance there was between the two. A voltmeter doesn't
put out much juice either and yet it still made it 25 feet or so through the
ground. 8-) Amazing.
Cheers,
Bill Parn
