1. Correction of Current Transformer Transient Performance / Wiszniewski, A ; Rebizant, W ; Schiel, L [ENY-ARTICLE-2008-202]
If a current transformer (CT) saturates while transforming the heavy primary current, in each period, there are sections when the magnetic core is unsaturated and transformation is correct, and when it is saturated, it causes enormous errors. [...]
