Re: [TCML] PT mA
Insertion of upstream reactance as a first order approximation model
converts PT into a
constant current power source (since you are limiting primary current).
current of 30A multiplied by inverse turns ration of primary/secondary
suggests maximum secondary current of ~ 0.25A. If you are boosting voltage
with a 120%
variac, current would likewise be boosted to nearly 300mA (0.291A).
Not exact, but will get you in the ball field.
