Discussion of "Accurate modeling of core-type distribution transformers for electromagnetic transient studies"

The author believes that the original authors should be commended for their interesting paper on transformer modeling (see ibid., vol.17, p.969-76, 2002). They have proposed an electromagnetic (EM) transients model with parameters determined by measurements. The model is intended to describe the transformer's behavior at the high frequencies of lightning surges and of particular interest is the transferred voltage from primary to secondary. Therefore, he argues that the original authors can properly neglect the effects due to core saturation and hysteresis without introducing large errors.
