If saturated, the surge current will flow longer than 1/4 cycle and will persist for more cycles too... "
? How does high current saturate the core, volt - seconds stay the same?
Look at the B-H curves for the various magnetic materials and you will see the B field is controlled by the amp-turns which changes the permeability of the core and induced voltage.
We are talking transient conditions and not steady state...
Why do you think current has no effect?
