Abstract
The principle of a novel comparator-type calibrator is described. It consists of a conventional current comparator-based high-precision current transformer calibration device with an additional current comparator and a current-voltage conversion circuits. The measuring range of the current is extended by the current comparator and that of the voltage by the resistances.
