The paper presents a digital apparatus for measuring current transformer errors in the range of frequencies between 50 and 1,250 Hz employing wattmetrical techniques: ratio and angle errors are calculated with accuracies of 10** minus **4 and 0. 1 prime respectively. Experimental results show the influence of different parameters which affect the measurement's accuracy; it the possibility of improving the accuracy of the device in the same range of frequency is foreseen.
