Yes! Sven, if you isolate the windings and capacitor from a "ground path
" with the transformer iron grounded via earth ground! You have to use
a scope to determine when you get "supersaturation" on the B/H curve.
To simulate the motor "locked rotor" condition "Super saturation" you
would have to have a matched secondary which is "shorted" to drive iron
into saturation! Transformers are not as easy to drive into "super
saturation as is motors! Hector will tell you that you will know it
when you hear "The pig squeal"! Just as a miss tuned "RV" it will
"Growl at you", "big time"!
