Critical Inductance

Posted by Sector-7G on June 18, 2002 at 11:38:51:
Hey-Hey!!!,
I've been looking at this set up since you posted questions. I think that the half of the transformer winding--CT to leg in question, must have this inductance. THe other side is carrying little if any current to contribute to magnetizing things in the core. Another concern is the DC content, a 'regular' iron cored choke has a substantiol air gap, usually the E's and I's arranged seperately and spaced with some paper. A power trans won't have this air gap and will behave more like a swing choke, high inductance until current flows. This might be a good thing...as the critical inductance increases with decreasing current, the inductance will also increase with less current. I have a 2 kV power trans I am going to experiment on, it is a big one, about 10 kg, I think that the primary should be left open or with BIG resistor actoss it, will try both ways. Any suggestions for experiment set ups?
regards,
Douglas
