Abstract
The paper deals with special features of transients in current transformer groups of differential busbar and busway protection. The unfaulted phases currents nature is described. The methods of determining of current transformer deep saturation condition and of these protections input currents extreme distortion condition are proposed. The methods described allow initial information obtaining necessary for stable protections algorithms development.
