How do I know if a transformer is saturated? I am doing the simulation of the saturation of a transformer, but what parameter tells me when a transformer is saturated? How do you calculate? is on the plate?, there is a rule that can help me? How could model? I understand the saturation occurs when the flow can no longer bind to the other winding, this is given to certain current, this current is the same that appears as the highest in the bale of features? Thank you for your help Eduardo Alvarez Guatemala
