Hi Mark,

Original poster: "Mark Dunn" <mdunn@xxxxxxxxxxxx>

Thanks for all your help. Now if you can bear with me and help me solve the original problem with the math(BTW <> is "not equal to")....

I have (2) inductors in series. My current limiter and my transformer. Mains is 120V/60 Hz/1 ph.

The current limiter is 15 mH, X = 5.65 Ohms, R = 0.3 Ohms. The transformer is Z = 1.2 Ohms, R = 0.3 Ohms, so X = 1.16 Ohms

So System Impedence Z = 6.82 Ohms

This gives I = 120/6.82 = 17.6 Amps and is near exactly what I am getting.

The measured voltage between the inductor and transformer is about 90 to 95 volts. Have gotten as high a 100 volts. This is the voltage drop across the transformer. This is inconsistent with the above values and in fact seems reversed from what the math suggests. I have double checked it.
