Abstract :
The author believed that the original authors should be commended for their interesting paper on transformer modeling (see ibid., vol.17, p.969-76, 2002). He stated how they had proposed an electromagnetic (EM) transients model with parameters determined by measurements. The model was intended to describe the transformer´s behavior at the high frequencies of lightning surges and of particular interest was the transferred voltage from primary to secondary. Therefore, he argued that the authors could properly neglect the effects due to core saturation and hysteresis without introducing large errors. The original authors´ response to this discussion is presented as closure.
