Re: Mains Current Monitoring

"I'll track down some data for ferrites (Fair-Rite, Amidon, and
would be likely suppliers, by the way), but for silicon steel: 12000 A/m
1.8T, or 4500 A/m -at- 1.5T depending on the kind and form of steel, which
affects the losses: first number for 3.6 W/kg -at- 1 T, the second is for
W/kg-at-1T (both at 50Hz)

Amidon doesn't have their info on their web site, but they'll fax it to
if you call them."

        They had design info on  ferrites and powdered iron materials the last
time I looked.  Wonder if you overlooked it?
