Abstract :
This paper presents a non-invasive method for calibrating AC clamp meters for power and energy measurements. A procedure for determining the ratio error and the phase displacement in a wider frequency range up to 10 kHz is also analyzed. The results of measurements of both types of error for two clamp meters are presented at the end of the paper.
