Abstract :
A high-accuracy system for calibration of Rogowski coils using current transformers and digital sampling is described in the paper. An automated version of the calibration system is capable of operating at currents up to 2,000 A, at power frequencies. A semi-automated version is capable of operating at currents up to 60,000 A. The uncertainty of the calibration system is estimated to be better than 100ldr10-6.
