Abstract :
A scheme is presented employing two precision resistors and an electronic amplifier for reducing the ratio and phase-angle errors in a current transformer. The amplifier supplies only the error current. The proposed arrangement facilitates the adaptability of inexpensive low ampere-turn c.t.s for calibration work in the laboratory.
