I am aware that source impedance is a determining factor when considering inrush. I was wondering if there is a correlation between the two that would provide one with a ballpark of what the inrush current will be more or less based on source impedance and transformer rated current (Ir).
I am aware that the inrush current is also dependent on other factors such as transformer design, core material, point-on-wave of energisation.
Thus allowing for all these (assuming worst case) and given that the primary voltage is x volts, Ir = y amps, source impedance = Zs (positive sequence) is there a way of deriving a ballpark figure for the inrush current?
Thanks.
