ABSTRACT:
Across current compensation control system includes a cross current detection compensator having an input terminal to which a cross connection line that cross-connects the secondary sides of auxiliary current transformers (CTs) are connected, and an output terminal to which cross current compensation lines that connect the secondary sides of CTs in series are connected, in which the cross current detection compensator supplies a compensation current to the cross current compensation line so as to cancel the current component corresponding to the cross current that appears at the secondary sides of the CTs when detecting the cross current that circulates within a bus bar, a distribution line, and a switch.
