Abstract
The drift of the error of a window-type high current transformer(CT) was observed by an automated calibration system that consists of a current comparator(CC) [1] and a current ratio transfer standard(CRTS) [2]. Furthermore, the shielding by means of aluminum plates for preventing local magnetic saturation is also proposed in this paper.
