The overexcitation of a transformer can damage the transformer if the event is allowed to persist. Overexcitation results in excessive core flux resulting in a high interlamination core voltage, which, in turn, results in iron burning. Also, at this high flux level, the normal magnetic iron path designed to carry flux saturates and the flux begins to flow in leakage paths not designed to carry it, again causing damage. Figure 12 illustrates this flux path
