Abstract :
W.C. Kotheimer comments on the paper by U.D. Annakkage et al. (see ibid., vol.15, no.1, p.57-61, 2000). The author points out that the original authors have identified an apparent limitation of the Jiles-Atherton algorithm using the Langevin function when used to model the core of a current transformer subjected to high fault currents in the presence of a significant amount of remanence. The original authors reply to the comments.
