Re: Unused Winding Autotransformer Warning
I can't agree with you here. I've been doing it for years (over 10kVA)
and Bill Wysock has been doing it since I was a teenager! (up to
100kVA!). All with series variacs as current control. Your comments
suggest massive failure in the field and we just don't see that in the
practical application of TC science.
