Webreduce and saturation is removed. CT, Line, and Relay Impedances In Figure 1 the CT primary impedances and secondary reactance are shown but are com-monly negligible. This reasonably accurate representation is used herein. However, only when a CT has “fully distributed” windings can the CT secondary reactance be considered WebFig 5: Saturation and Hysteresis Curves for 2000-5A CT Fig. 6 Saturation and Hysteresis Curves for 600-5A CT V.
