22 amp peak surge in the first half cycle.

I posted this SAME link to YOU three days ago.

Standard 100VA toroidals for 120 VAC power have a 6 ohm primary resistance.

You stupid ****head !!

I can't believe you'd actually say something like that, especially when
you (hypocritically) failed to actually do the EXPERIMENT I mentioned.
Some people, and their arrogance. I thought you were ABOVE that. I
guess not.

I've posted the result of an experiment over on ABSE showing the surge due to
saturation of the core of a toroidal power transformer.

** Problem is, almost no-one has access that NG - cos the major ISPs
dropped binaries years ago.

Post it elsewhere and give us a link.

I have a nice JPEG of a DSO screen for a 1KVA conventional transformer.

Shows a half cycle peak of +115 amps ( 240 VAC supply ) then a +30 amp peak
then a +5 amp one etc - all lined up with zero crossings of the AC
voltage.
