Hi Jim, I must disagree with your post. The advice is often given to determine an NST's secondary voltage by feeding 120VAC to the secondary and measuring the resulting Vprimary, this makes sense. However, having tried this, it doesn't work. There's some very non-linear stuff going on with NST's, even well below saturation. There was a thread on this topic several years ago, I don't recall the resolution.
Interesting...I haven't encountered this.. I've measured a variety of high leakage inductance transformers.. although only one NST.
